?(3)-Oxido-hexa-?(2)-pivalato-tris[(methanol-?O)cobalt(III)] chloride.

ABSTRACT: The crystal structure of the title compound, [Co(3)(C(5)H(9)O(2))(6)O(CH(4)O)(3)]Cl, consists of trinuclear Co(III) complex cations and chloride anions. The Co(III) cation has site symmetry m, and is coordinated by four oxygen atoms from four bridging pivalate groups, one central O anion and a methanol oxygen atom, forming a distorted octa-hedral geometry. The coordinated methanol mol-ecule is located on a crystallographic special position, the C and O atoms being located on the mirror plane. The central O anion lies in the crystallographic position, and acts as a ?(3)-O bridge, linking three equivalent Co(III) cations and generating the oxo-centered trinuclear Co(III) complex. The chloride anion, which acts as the counter-ion, is located on crystallographic position. O-H?Cl hydrogen bonding between the Cl anion and hydroxyl group of the coordinated methanol mol-ecule links the mol-ecules into a supra-molecular network.

Project description:The title compound, [Co(C(2)H(8)N(2))(3)](2)[SiMo(8)V(4)O(40)(VO)(2)]·6H(2)O, was prepared under hydro-thermal conditions. The asymmetric unit consists of a transition metal complex [Co(en)(3)](3+) cation (en is ethyl-enediamine), one half of an [SiMo(8)V(4)O(40)(VO)(2)](6-) heteropolyanion, two solvent water mol-ecules in general positions and two half-mol-ecules of water located on a mirror plane. In the complex cation, the Co(3+) ion is in a distorted octa-hedral coordination environment formed by six N atoms of the three chelating en ligands. One of the en ligands exhibits disorder of its aliphatic chain over two sets of sites of equal occupancy. The [SiMo(8)V(4)O(40)(VO)(2)](6-) heteropolyanion is a four-electron reduced bivanadyl-capped ?-Keggin-type molybdenum-vanadium-oxide cluster. In the crystal, it is located on a mirror plane, which results in disorder of the central tetra-hedral SiO(4) group: the O atoms of this group occupy two sets of sites related by a mirror plane. Furthermore, all of the eight ?(2)-oxide groups are also disordered over two sets of sites with equal occupancy. There are extensive inter-molecular N-H?O hydrogen bonds between the complex cations and inorganic polyoxidoanions, leading to a three-dimensional supra-molecular network.

Hexakis(1H-imidazole-?N)cobalt(III) tris-(hexa-fluoridophosphate) hexa-hydrate.

Project description:In the crystal structure of the title compound, [Co(C(3)H(4)N(2))(6)](PF(6))(3)·6H(2)O, the Co(III) atom lies on a special position with site-symmetry and the P atom is located on a special position with site symmetry . The Co(III) atom has an almost ideal octa-hedral coordination formed by the N atoms of six imidazole ligands. The water mol-ecules form hydrogen-bonded helical chains propagating in [001] by O-H?O inter-actions with a distance of 2.913?(2)?Å. They simultaneously inter-act as hydrogen-bond acceptors and donors with the cations and anions, respectively, resulting in the formation of a three-dimensional assembly. Weak C-H?F inter-actions further stabilize the crystal structure.

Project description:The title compound, [Co(III)(NH?)?]?[Co(II)(C?O?)?]?Cl·12H?O, was synthesized under hydro-thermal conditions. The asymmetric unit comprises two [Co(NH?)?]³? cations, one located on a threefold axis and the other on a site of symmetry -3, a [Co(C?O?)?]?? anion, located on a threefold axis, one sixth of a chloride anion [disordered over two sites, one threefold (site occupancy = 0.5) and the other -3 (site occupancy (0.25)] and two water molecules. Both Co(III) centers are six-coordinated by NH? mol-ecules, forming [Co(NH?)?]³? octa-hedra, with Co-N distances in the range 1.958?(2)-1.977?(3)?Å. The title structure gives the first example of the [Co(C?O?)?]?? anion, with the distorted octa-hedral environment of Co(II) center formed by six O atoms from three oxalate residues.

Low-temperature redetermination of hexa-kis(?-chloro-acetato-?O:O')-?(3)-oxido-tris[aquachromium(III)] nitrate 3.5-hydrate.

Project description:A low-temperature redetermination of the trinuclear cluster compound described as [Cr(3)(C(2)H(2)ClO(2))(6)O(H(2)O)(3)]NO(3)·3H(2)O [Glowiak, Kubiak & Jezowska-Trzebiatowska (1977 ?). Bull. Acad. Pol. Sci. Ser. Sci. Chim.25, 359-371] shows that the salt is a 3.5-hydrate, [Cr(3)(C(2)H(2)ClO(2))(6)O(H(2)O)(3)]NO(3)·3.5H(2)O. The trinuclear cluster cation is disordered in four of the six monochloro-acetate groups. One is disordered over two positions in respect of the chloro-methyl atoms (occupancy ratio 0.50:0.50); another is disordered over three positions in respect of the chloro-methyl atoms (occupancy ratio 0.50:0.37:0.13) whereas two are disordered over two positions in respect of the Cl atoms only (occupancy ratios 0.84:0.16 and 0.60:0.40). Of the four independent uncoordinated water mol-ecules, one has an occupancy factor of 0.5. The trinuclear cation has an oxido O atom that is connected to three water-coordinated Cr(III) atoms, the three metal atoms forming the points of an equilateral triangle. Six carboxyl-ate groups each chelate a Cr-O-Cr fragment. The cations, anions and uncoordinated water mol-ecules are linked by hydrogen bonds.
