Bis(4-amino-pyridinium) μ6-oxido-dodeca-μ2-oxido-hexaoxido[rhenium(VII)tetratungsten(VI)vanadium(V)]ate hepta-hydrate.

ABSTRACT: In the title organic-inorganic hybrid compound, (C5H7N2)2[ReVW4O19]·7H2O, the Lindqvist-type polyoxido anion has crystallographically imposed mm2 symmetry and is built up by six MO6 (M = W, V, Re) edge-sharing distorted octa-hedra. The Re and V atoms share the same crystallographic site in a 0.5:0.5 ratio. The 4-amino-pyridinium cations lie on a mirror plane. Three of the four independent water O atoms in the asymmetric unit are located on a mirror plane whereas the remaining O atom has mm2 site symmetry. In the crystal, the cations, anions and water mol-ecules are linked into a three-dimensional network through O-H⋯O and N-H⋯O hydrogen-bonding inter-actions.

Project description:In the title salt, [Eu(C3H7NO)8][PMo12O40], the asymmetric unit comprises one α-Keggin-type [PMo12O40](3-) polyoxidometalate anion and one distorted dodeca-hedral [Eu(C3H7NO)8](3+) complex cation. In the crystal, the isolated polyoxidometalate anions are packed into hexa-gonally arranged rows extending parallel to [001]. The complex cations are situated between the rows and are linked to the neighbouring anions through weak C-H⋯O hydrogen-bonding inter-actions, leading to the formation of a three-dimensional network structure.

Hexakis(2-amino-pyridinium) di-μ(6)-oxido-tetra-μ(3)-oxido-tetra-deca-μ(2)-oxido-octa-oxidodeca-vanadium(V) dihydrate.

Project description:In the title compound, (C(5)H(7)N(2))(6)[V(10)O(28)]·2H(2)O, the [V(10)O(28)](6-) anion is generated by crystallographic inversion symmetry and each of the five vanadium centres adopts a distorted VO(6) octa-hedral geometry. In the crystal structure, a network of N-H⋯O, N-H⋯(O,O) and O-H⋯O hydrogen bonds helps to establish the packing.

Penta-ammonium hepta-sodium bis-[penta-kis(μ(2)-oxido)deca-oxido-bis-(μ(5)-phosphato)penta-molybdenum(VI)] henicosa-hydrate.

Project description:The title compound, (NH(4))(5)Na(7)[Mo(5)P(2)O(23)](2)·21H(2)O, was prepared under atmospheric conditions in aqueous solution at room temperature. The structure contains the [Mo(5)P(2)O(23)](6-) heteropolyoxometallate anion, which has been previously reported a number of times with a variety of differing counter-cations. Each anion is built up of five MoO(6) octa-hedra sharing an edge and forming a ring which is closed by common corners of the terminal octa-hedra. The rings are closed on both sides by two asymmetric PO(4) tetra-hedra, sharing three corners with three MoO(6) octa-hedra. The anions are chiral and the two independent anions in the asymmetric unit were arbitarily chosen with the same chirality, but the centrosymmetric crystal contains both enanti-omers. The structure can alternatively be described as a succession of layers parallel to (101), formed by the [Mo(5)P(2)O(23)](6-) anions and linked by sodium chains. Water mol-ecules and ammonium ions fill the remaining space and ensure the cohesion through extensive N-H⋯O and O-H⋯O hydrogen bonding.

Crystal structure of poly[μ6-adipato-di-aquadi-μ2-oxalato-didysprosium(III)].

Project description:In the title coordination polymer, [Dy2(C6H8O4)(C2O4)2(H2O)2] n , the asymmetric unit consists of one Dy(3+) cation, one half of an adipate anion, two halves of oxalate anions and one coordinating water mol-ecule. The adipate and oxalate ions are located on centres of inversion. The Dy(3+) cation has a distorted tricapped trigonal-prismatic geometry and is coordinated by nine O atoms, four belonging to three adipate anions, four to two oxalate anions and one from an aqua ligand. The cations are bridged by adipate ligands, generating a two-dimensional network parallel to (010). This network is further extended into three dimensions by coordination of the rigid oxalate ligands and is further consolidated by O-H⋯O hydrogen bonds. A part of the adipate anion is disordered over two positions in a 0.75:0.25 ratio.

Crystal structure of poly[[{μ2-1,4-bis[(1H-imid-azol-1-yl)methyl]benzene}[μ6-5-(4-carboxylatophenoxy)isophthalato]-μ3-hydroxido-dicobalt(II)] 0.25-hydrate].

Project description:The title coordination polymer, {[Co2(C15H7O7)(OH)(C14H14N4)]·0.25H2O} n , was synthesized under hydro-thermal conditions. The asymmetric unit contains two Co(2+) ions, one L (3-) anion originating from 5-(4-carb-oxy-phen-oxy)isophthalic acid (H3 L), one OH(-) ligand, one 1,4-bis-[(1H-imidazol-l-yl)meth-yl]benzene (bix) ligand and one disordered lattice water mol-ecule (occupancy 0.25). The two Co(2+) ions have different environments. One has an octa-hedral O4N2 coordin-ation sphere, defined by four O atoms from three carboxyl-ate groups and one OH(-) ligand, and two N atoms from two symmetry-related bix ligands. The other has a trigonal-bipyramidal O5 coordination sphere resulting from three carboxyl-ate groups and two OH(-) ligands. The dihedral angles between the two benzene rings in the L (3-) ligand and between the benzene ring and the two imidazole rings in the bix ligand are 67.05 (15), 75.27 (17) and 82.05 (17)°, respectively. Four neighbouring Co(2+) ions are linked by six carboxyl-ate groups and two μ 3-OH ligands, forming a butterfly-shaped secondary building unit (SBU). These SBUs are connected by L (3-) anions into layers parallel to (1-10). Adjacent layers are cross-linked by the bix ligands, forming a three-dimensional framework that has a bimodal (3,8)-connected tfz-d topology. The disordered lattice water mol-ecule is located in the voids of the framework and has O⋯O and O⋯N contacts of 2.81 (2) and 2.95 (2) Å, suggesting medium-strength hydrogen bonds. The title compound may be a good candidate for artificial eye lenses.

Tris-(4,4'-di-tert-butyl-2,2'-bi-pyridine)(trans-4-tert-butyl-cyclo-hexa-nolato)-deca-μ-oxido-hepta-oxido-hepta-vanadium aceto-nitrile monosolvate including another unknown solvent mol-ecule.

Project description:The title hepta-nuclear alkoxido(oxido)vanadium(V) oxide cluster complex, [V7(C10H19O)O17(C18H24N2)3]·CH3CN, was obtained by the reaction of [V8O20(C18H24N2)4] with 4-tert-butyl-cyclo-hexa-nol (mixture of cis and trans) in a mixed CHCl3/CH3CN solvent. The complex has a V7O18N6 core with approximately C s symmetry, which is composed of two VO4 tetra-hedra, two VO6 octa-hedra and three VO4N2 octa-hedra. In the crystal, these complexes are linked together by weak inter-molecular C-H⋯O hydrogen bonds between the 4,4'-di-tert-butyl-2,2'-bi-pyridine ligand and the V7O18N6 core, forming a one-dimensional network along the c-axis direction. Besides the complex, the asymmetric unit contains one CH3CN solvent mol-ecule. The contribution of other disordered solvent mol-ecules to the scattering was removed using the SQUEEZE option in PLATON [Spek (2015 ▸). Acta Cryst. C71, 9-18]. The unknown solvent mol-ecules are not considered in the chemical formula and other crystal data.
