Synthesis and redetermination of the crystal structure of NbF₅.

ABSTRACT: Single crystals of NbF₅, niobium(V) fluoride, have been obtained by the reaction of niobium metal in a stream of dilute elemental fluorine at 473 K and subsequent sublimation. The as-obtained bulk phase compound was shown to be pure by powder X-ray diffraction at 293 K and by IR and Raman spectroscopy. A single-crystal X-ray analysis was conducted at 100 K. In comparison to the previously reported structure model [Edwards (1964 ▸). J. Chem. Soc. pp. 3714-3718], the lattice parameters and fractional atom coordinates were determined to much higher precision and individual, anisotropic displacement parameters were refined for all atoms.

Redetermination of the crystal structure of K2Hg(SCN)4.

Project description:Single crystals of K2Hg(SCN)4 [dipotassium tetra-thio-cyanato-mercurate(II)] were grown from aqueous solutions of potassium thio-cyanate and mercury(II) thio-cyanate and studied by single-crystal X-ray diffraction. In comparison with the previously reported structure model [Zvonkova (1952 ▸). Zh. Fiz. Khim. 26, 1798-1803], all atoms in the crystal structure were located, with lattice parameters and fractional coordinates determined to a much higher precision. In the (crystal) structure, the HgII atom is located on a twofold rotation axis and is coordinated in the form of a distorted tetra-hedron by four S atoms of the thio-cyanate anions. The K+ cation shows a coordination number of eight.

Crystal structure of Hg2SO4 - a redetermination.

Project description:The crystal structure of mercury(I) sulfate (or mercurous sulfate), Hg2SO4, was re-determined based on modern CCD data. In comparison with the previous determination from Weissenberg film data [Dorm (1969 ▶). Acta Chem. Scand. 23, 1607-1615], all atoms were refined with anisotropic displacement parameters, leading to higher precision in terms of bond lengths and angles [e.g. Hg-Hg = 2.5031 (7) compared to 2.500 (3)Å]. The structure consists of alternating rows along [001] of Hg2 (2+) dumbbells (generated by inversion symmetry) and SO4 (2-) tetra-hedra (symmetry 2). The dumbbells are linked via short O-Hg-Hg-O bonds to the sulfate tetra-hedra into chains extending parallel to [20-1]. More remote O-Hg-Hg-O bonds connect these chains into a three-dimensional framework.

Redetermination of the crystal structure of NbF4.

Project description:Single crystals of NbF4, niobium(IV) tetra-fluoride, were synthesized by disproportionation of Nb2F5 at 1273 K in a sealed niobium tube, extracted and studied by single-crystal X-ray diffraction. Previous reports on the crystal structure of NbF4 were based on X-ray powder diffraction data and the observed isotypicity to SnF4 [Gortsema & Didchenko (1965 ▸). Inorg. Chem. 4, 182-186; Schäfer et al. (1965 ▸). J. Less Common Met. 9, 95-104]. The data obtained from a single-crystal X-ray diffraction study meant the atomic coordinates could now be refined as well as their anisotropic displacement parameters, leading to a significant improvement of the structural model of NbF4. In the structure, the Nb atom is octahedron-like surrounded by six F atoms of which four are bridging to other NbF6 octa-hedra, leading to a layer structure extending parallel to the ab plane.

Crystal structure of CdSO4(H2O): a redetermination.

Project description:The crystal structure of the title compound, cadmium sulfate monohydrate or poly[(μ2-aqua)(μ4-sulfato)-cadmium], was redetermined based on modern CMOS (complementary metal oxide silicon) data. In comparison with the previous study [Bregeault & Herpin (1970 ▸). Bull. Soc. Fr. Mineral. Cristallogr. 93, 37-42], all non-H atoms were refined with anisotropic displacement parameters and the hydrogen-bonding pattern unambiguously established due to location of the hydrogen atoms. In addition, a significant improvement in terms of precision and accuracy was achieved. In the crystal, the Cd(2+) cation is coordinated by four O atoms of four sulfate anions and two O atoms of water mol-ecules, forming a distorted octa-hedral trans-[CdO6] polyhedron. Each sulfate anion bridges four Cd(2+) cations and each water mol-ecule bridges two Cd(2+) cations, leading to the formation of a three-dimensional framework, with Cd⋯Cd separations in the range 4.0757 (2)-6.4462 (3) Å. O-H⋯O hydrogen-bonding inter-actions of medium strength between the coordinating water mol-ecules and sulfate anions consolidate the crystal packing.

Diterbium hepta-nickel: a crystal structure redetermination.

Project description:The crystal structure of the title compound, Tb2Ni7, was redetermined from single-crystal X-ray diffraction data. In comparison with previous studies based on powder X-ray diffraction data [Lemaire et al. (1967). C. R. Acad. Sci. Ser. B, 265, 1280-1282; Lemaire & Paccard (1969). Bull. Soc. Fr. Mineral. Cristallogr. 92, 9-16; Buschow & van der Goot (1970). J. Less-Common Met. 22, 419-428], the present redetermination affords refined coordinates and anisotropic displacement parameters for all atoms. A partial occupation for one Tb atom results in the non-stoichiometric composition Tb1.962 (4)Ni7. The title compound adopts the Ce2Ni7 structure type and can also be derived from the CaCu5 structure type as an inter-growth structure. The asymmetric unit contains two Tb sites (both site symmetries 3m.) and five Ni sites (.m., mm2, 3m., 3m., -3m.). The two different coordination polyhedra of Tb are a Frank-Kasper polyhedron formed by four Tb and 12 Ni atoms and a pseudo Frank-Kasper polyhedron formed by two Tb and 18 Ni atoms. The four different coordination polyhedra of Ni are Frank-Kasper icosa-hedra formed by five Tb and seven Ni atoms, four Tb and eight Ni atoms, three Tb and nine Ni atoms, and six Tb and six Ni atoms, respectively.

Redetermination of the crystal structure of RhPb2 from single-crystal X-ray diffraction data, revealing a rhodium deficiency.

Project description:RhPb2 (rhodium dilead) is a superconductor crystallizing in the CuAl2 structure type (space group I4/mcm). The Rh and Pb atoms are located at the 4a (site symmetry 422) and 8h (m.2m) sites, respectively. The crystal structure is composed of [RhPb8] anti-prisms, which share their square faces along the c axis and the edges in the direction perpendicular to the c axis. We have succeeded in growing single crystals of RhPb2 and have re-determined the crystal structure on basis of single-crystal X-ray diffraction data. In comparison with the previous structure studies using powder X-ray diffraction data [Wallbaum (1943 ▸). Z. Metallkd. 35, 218-221; Havinga et al. (1972 ▸). J. Less-Common Met. 27, 169-186], the current structure analysis of RhPb2 leads to more precise unit-cell parameters and fractional coordinates, together with anisotropic displacement parameters for the two atoms. In addition and likewise different from the previous studies, we have found a slight deficiency of Rh in RhPb2, leading to a refined formula of Rh0.950 (9)Pb2.

Redetermination of the crystal structure of yttrium chromium tetra-boride, YCrB4, from single-crystal X-ray diffraction data.

Project description:The structural parameters of yttrium chromium tetra-boride YCrB4 were refined based on single-crystal X-ray diffraction data. YCrB4 is ortho-rhom-bic, having a space group of type Pbam (No. 55) and with lattice parameters of a = 5.9425 (2), b = 11.4831 (4), c = 3.4643 (1) Å. The Y and Cr atoms are located at Wyckoff 4h sites (x, y, 0) and B atoms at the Wyckoff 4g sites (x, y, 1/2). The first structural investigation of YCrB4 was performed using a single crystalline sample [Kuz'ma, (1970 ▸). Kristallografiya. 15, 372-374]. The present study successfully refined all the positional and atomic displacement parameters of the Y, Cr, and B atoms.

Redetermination and new description of the crystal structure of vanthoffite, Na6Mg(SO4)4.

Project description:The crystal structure of vanthoffite {hexa-sodium magnesium tetra-kis[sulfate-(VI)]}, Na6Mg(SO4)4, was solved in the year 1964 on a synthetic sample [Fischer & Hellner (1964 ▸). Acta Cryst. 17, 1613]. Here we report a redetermination of its crystal structure on a mineral sample with improved precision. It was refined in the space group P21/c from a crystal originating from Surtsey, Iceland. The unique Mg (site symmetry ) and the two S atoms are in usual, only slightly distorted octa-hedral and tetra-hedral coordinations, respectively. The three independent Na atoms are in a distorted octa-hedral coordination (1×) and distorted 7-coordinations inter-mediate between a 'split octa-hedron' and a penta-gonal bipyramid (2×). [MgO6] coordination polyhedra inter-change with one half of the sulfate tetra-hedra in <011> chains forming a (100) meshed layer, with dimers formed by edge-sharing [NaO7] polyhedra filling the inter-chain spaces. The other [NaO7] polyhedra are organized in a parallel layer formed by [010] and [001] chains united through edge sharing and bonds to the remaining half of sulfate groups and to [NaO6] octa-hedra. The two types of layers inter-connect through tight bonding, which explains the lack of morphological characteristics typical of layered structures.

Crystal structure of lead(II) tartrate: a redetermination.

Project description:Single crystals of poly[μ4-tartrato-κ(6) O (1),O (3):O (1'):O (2),O (4):O (4')-lead], [Pb(C4H4O6)] n , were grown in a gel medium. In comparison with the previous structure determination of this compound from laboratory powder X-ray diffraction data [De Ridder et al. (2002 ▶). Acta Cryst. C58, m596-m598], the redetermination on the basis of single-crystal data reveals the absolute structure, all atoms with anisotropic displacement parameters and a much higher accuracy in terms of bond lengths and angles. It could be shown that a different space group or incorporation of water as reported for similarly gel-grown lead tartrate crystals is incorrect. In the structure, each Pb(2+) cation is bonded to eight O atoms of five tartrate anions, while each tartrate anion links four Pb(2+) cations. The resulting three-dimensional framework is stabilized by O-H⋯O hydrogen bonds between the OH groups of one tartrate anion and the carboxyl-ate O atoms of adjacent anions.

Redetermination of the crystal structure of NaTcO4 at 100 and 296 K based on single-crystal X-ray data.

Project description:The redetermination of the title compound, sodium pertechnate, from single-crystal CCD data recorded both at 296 and 100 K confirms previous studies based on X-ray powder diffraction film data [Schwochau (1962 ▸). Z. Naturforsch. Teil A, 17, 630; Keller & Kanellakopulos (1963 ▸). Radiochim. Acta, 1, 107-108] and neutron powder diffraction data using the Rietveld method [Weaver et al. (2017 ▸). Inorg. Chem.12, 677-681], but reveals a considerable improvement in precision. The standard uncertainties of the room-temperature structure determination are about seven times lower than those of the neutron diffraction structure determination and about 13 times lower at 100 K, due to the decrease in the amplitude of librations. The crystal expansion could be approximated linearly with a thermal volumic expansion coefficient of 1.19 (12) × 10-4 K-1. NaTcO4 adopts the scheelite (CaWO4) structure type in space group type I41/a with Na and Tc atoms (both with site symmetry -4) replacing Ca and W atoms, respectively.
