cyclo-Tetra-kis-(μ-2,4,6-tri-methyl-phenyl-κC ¹:κC ¹)bis-(tri-methyl-phosphane)-1κP,3κP-tetra-copper(I).

ABSTRACT: The title compound, [Cu₄(C₉H₁₁)₄(C₃H₉P)₂] or [Cu₄(Mes)₄(PMe₃)₂] (Mes = 2,4,6-tri-methyl-phenyl), was synthesized from copper(I) mesityl and tri-methyl-phosphane in THF as solvent. The mol-ecular structure of the complex has C ₂ symmetry and consists of four copper(I) atoms bridged by four μ-mesityl groups, giving an eight-membered puckered {Cu₄C₄} ring. Additionally, two copper(I) atoms at opposite corners of the Cu₄ rhomb are each linked to a terminal PMe₃ ligand. The PMe₃-bearing copper(I) atoms exhibit a distorted trigonal-planar coordination mode whereas the remaining Cu atoms linked to two mesityl groups are nearly linearly coordinated.

Bis(μ4-adamantane-1,3-dicarboxylato-1κO1:2κO1′:3κO3:4κO3′)octacarbonyl-1κ2C,2κ2C,3κ2C,4κ2C-tetrakis[tris(4-methylphenyl)phosphane]-1κP,2κP,3κP,4κP-tetraosmium(I)(2 Os–Os)

Project description:[Os2(CO)4(tri-p-tolylphosphine)2]2(μ4-adamantane-1,3-dicarboxylate)2 is a molecular loop consisting of two parallel diosmium(I) sawhorse units linked together by two bridging dicarboxylato ligands. The title compound is only the second example of a Group 8 dinuclear sawhorse complex with an adamantane-based dicarboxylato ligand. The title complex, [{Os2(CO)4(C21H21P)2}2(C12H14O4)2], is a centrosymmetric molecular loop consisting of two Os—Os sawhorse units linked by two adamantane dicarboxylato bridges. It was synthesized by the microwave-mediated reaction between Os3(CO)12 and adamantane-1,3-dicarboxylic acid. In contrast to the related complex [{Os2(CO)6}2(μ4-adamantane-1,3-diacetate)2], the metal–metal axes within each molecule are oriented parallel rather than perpendicular to one another. The crystal structure exhibits cavities that contain residual electron density peaks, but it was not possible to unambiguously identify the solvent therein. The contribution of the disordered solvent molecules to the scattering was removed using the SQUEEZE (Spek (2015 ▸). Acta Cryst. C71, 9–18) routine in PLATON [Spek (2020 ▸). Acta Cryst. E76, 1–11]. These solvent molecules are not considered in the given chemical formula and other crystal data.

Project description:In the title compound, [Pb(C(10)H(11)O(2))(2)](n) or [Pb(hino)(2)](n), the lead(II) ion is chelated by two hinokitiolate ligands in a distorted square-pyramidal configuration, with Pb-O bond lengths in the range 2.327 (6)-2.479 (9) Å. The 6s(2) lone electron pair of the lead(II) ion becomes stereochemically active and is directed towards the apex of this pyramid. The crystal structure of the title compound consists of chains formed by the bis-(hinokitiolato)lead(II) mol-ecules situated along the twofold screw axis. The coordination sphere around the lead(II) ion is completed by three additional O atoms, at 2.625 (7), 3.016 (8) and 3.064 (8) Å, from the two neighbouring Pb(hino)(2) units. Both isopropyl groups are rotationally disordered.

Synthesis, crystal structure and properties of bis(isoselenocyanato-κN)tetrakis(pyridine-κN)nickel(II)

Project description:In the crystal structure of the title compound, discrete centrosymmetric complexes are observed, in which the Ni cations are octahedrally coordinated by two terminal N-bonded selenocyanate anions and four pyridine coligands. The reaction of nickel chloride hexahydrate with potassium selenocyanate and pyridine in water leads to the formation of crystals of the title complex, [Ni(NCSe)2(C5H5N)4], which were characterized by single-crystal X-ray diffraction. Its crystal structure consists of discrete complexes, located on centers of inversion, in which the Ni cations are sixfold coordinated by two terminal N-bonded selenocyanate anions and four pyridine ligands within a slightly distorted octahedral coordination. In the crystal, the complexes are connected by weak C—H⋯Se interactions. PXRD investigations revealed that a pure crystalline phase has formed. In the IR and Raman spectra, the C—N stretching vibrations are observed at 2083 and 2079 cm−1, respectively, in agreement with the presence of only terminally bonded anionic ligands. Upon heating, one well-resolved mass loss is observed, in which two of the four pyridine ligands are removed, leading to a compound with the composition Ni(NCSe)2(C5H5N)2. In this compound, the C—N stretching vibration is shifted to 2108 cm−1 (Raman) and 2115 cm−1 (IR), indicating the presence of μ-1,3-bridging anionic ligands. In its PXRD pattern, very broad reflections are observed, indicating for poor crystallinity and/or very small particle size. This crystalline phase is not isotypic to its Co and Fe analogs.

Synthesis, crystal structure and thermal properties of tetrakis(3-methylpyridine-κN)bis(thiocyanato-κN)nickel(II)

Project description:In the crystal structure of the title compound, the nickel cations are octahedrally coordinated by two terminal N-bonded thiocyanate anions and four 3-methylpyridine ligands. Reaction of Ni(NCS)2 with 3-methylpyridine in water leads to the formation of crystals of the title compound, [Ni(NCS)2(C6H7N)4]. All of them are of poor quality and non-merohedrally twinned but a refinement using data in HKLF-5 format leads to a reasonable structure model and reliability factors. The crystal structure of the title compound consists of discrete complexes, in which the nickel cations are sixfold coordinated by two terminal N-bonded thiocyanate anions and four 3-methylpyridine ligands within slightly distorted octahedra. One of the 3-methylpyridine ligands is disordered and was refined using a split model. The discrete complexes are arranged into layers. X-ray powder diffraction proves that pure samples have been obtained, and in the IR spectrum, the CN stretching vibration is observed at 2072 cm−1, in agreement with the presence of only terminally coordinated thiocyanate anions. Comparing the calculated powder pattern with those of the residues obtained by solvent removal from several solvates already reported in the literature proves that, in each case, this crystalline phase is formed. Assessing the crystal structures of the solvates in comparison with that of the ansolvate reveals some similarities.

The CoII ion exhibits a distorted cis-CoN2O4 octahedral coordination environment and the Co⋯Co separation is 3.326 (2) Å.

Di-μ-chlorido-bis[(2,2′:6′,2′′-terpyridine-κ3N,N′,N′′)copper(II)] bis(trifluoromethanesulfonate)

Project description:The crystal structure of the centrosymmetric complex [Cu(terpy)2Cl2](OTF)2 consists of a CuII metal center in a distorted square-pyramidal geometry with π–π stacking interactions contributing to the crystal packing. In the centrosymmetric title complex, [Cu2Cl2(C15H11N3)2](CF3O3S)2, the CuII metal center is fivefold coordinated by two chloride ions and three nitrogen atoms of the terpyridine ligand in a distorted square-pyramidal geometry; two trifluoromethanesulfonate ions complete the outer coordination sphere. π–π stacking interactions between the pyridyl rings in adjacent molecules contribute to the alignment of the complexes in columns along the a-axis. This structure represents the first example of a binuclear dication of formula [Cu(terpy)2Cl2]2+ with trifluoromethanesulfonate as counter-ions.
