The Bi(III) coordination polyhedron is a distorted octa-hedron and two such octa-hedra share a triangular face to form the complex anion. There are three short terminal Bi-Cl bonds [2.5471?(6)-2.5781(5?Å] and three longer bridging bonds [2.8599?(5)-2.9984?(6)?Å] in each octa-hedron. Anions, cations and water mol-ecules are linked by hydrogen bonds to form a three-dimensional network. There are also ?-? stacking inter-actions between quinoline ring systems, with an inter-planar distance of 3.27?(1)?Å.

Bis(1,4-diazo-niabi-cyclo-[2.2.2]octa-ne) di-μ-chlorido-bis-[tetra-chlorido-anti-monate(III)] dihydrate.

Project description:The title salt, (C6H14N2)2[Sb2Cl10]·2H2O, was obtained by slow evaporation of an acidic solution of 1,4-di-aza-bicyclo-[2.2.2]octane and SbCl3. The crystal structure consists of (C6H14N2)(2+) cations, [Sb2Cl10](4-) double octa-hedra and lattice water mol-ecules. All mol-ecular components are situated on special positions. The cation and the lattice water mol-ecule exhibit mirror symmetry, whereas the anion has site symmetry 2/m. The cations, anions and water mol-ecules are alternately arranged into columns along [010]. Individual columns are joined into layers extending along (001). Intra-layer N-H⋯O and inter-layer N-H⋯Cl hydrogen-bonding inter-actions lead to the formation of a three-dimensional network.

Tri-μ-sulfato-κO:O'-bis-[aqua-(1,10-phenanthroline-κN,N')indium(III)] dihydrate.

Project description:In the title dinuclear In(III) compound, [In(2)(SO(4))(3)(C(12)H(8)N(2))(2)(H(2)O)(2)]·2H(2)O, each In(III) cation is coordinated by a 1,10-phenanthroline (phen) ligand, a water mol-ecule and three sulfate O atoms in a distorted InN(2)O(4) octa-hedral geometry. Three sulfate anions bridge two In(III) cations, forming the dinuclear entities. O-H⋯O and weak C-H⋯O hydrogen bonding is observed in the crystal structure. The crystal structure is further consolidated by π-π stacking between nearly parallel phen ring systems [dihedral angle = 4.2 (4)°], the centroid-centroid distance between benzene rings of adjacent phen ligands being 3.528 (9) Å.

μ-Oxido-bis-[hydridotris(tri-methyl-phosphane-κP)iridium(III)](Ir-Ir) bis-(tetra-fluorido-borate) dihydrate.

Project description:The title compound, [Ir2H2O(C3H9P)6](BF4)2·2H2O, was isolated from the reaction between [Ir(COD)(PMe3)3]BF4 and H2 in water (COD is cyclo-octa-1,5-diene). The asymmetric unit consists of one Ir(III) atom bonded to three PMe3 groups, one hydride ligand and half an oxide ligand, in addition to a BF4 (-) counter-ion and one water molecule of hydration. The single oxide ligand bridging two Ir(III) atoms is disordered across an inversion center with each O atom having a 50% site occupancy. Each Ir(III) atom has three PMe3 groups occupying facial positions, with the half-occupancy O atoms, a hydride ligand and an Ir-Ir bond completing the coordination sphere. The Ir-Ir distance is 2.8614 (12) Å, comparable to other iridium(III) metal-metal bonds. Two water mol-ecules hydrogen bond to two BF4 (-) anions in the unit cell.

Crystal structure of the new hybrid material bis-(1,4-diazo-niabi-cyclo-[2.2.2]octa-ne) di-μ-chlorido-bis-[tetra-chlorido-bis-muthate(III)] dihydrate.

Project description:The title compound bis-(1,4-diazo-niabi-cyclo-[2.2.2]octa-ne) di-μ-chlorido-bis-[tetra-chlorido-bis-muthate(III)] dihydrate, (C6H14N2)2[Bi2Cl10]·2H2O, was ob-tain-ed by slow evaporation at room temperature of a hydro-chloric aqueous solution (pH = 1) containing bis-muth(III) nitrate and 1,4-di-aza-bicyclo-[2.2.2]octane (DABCO) in a 1:2 molar ratio. The structure displays a two-dimensional arrangement parallel to (100) of isolated [Bi2Cl10](4-) bi-octa-hedra (site symmetry -1) separated by layers of organic 1,4-diazo-niabi-cyclo-[2.2.2]octane dications [(DABCOH2)(2+)] and water mol-ecules. O-H⋯Cl, N-H⋯O and N-H⋯Cl hydrogen bonds lead to additional cohesion of the structure.

catena-Poly[bis(1,3-benzo-thia-zol-3-ium) [[di-chlorido-anti-monate(III)]-di-μ-chlorido-μ-oxido-[chlorido-anti-monate(III)]-μ-chlorido]].

Project description:The title compound, {(C7H6NS)2[Sb2Cl6O]} n , contains two benzo-thia-zolidium cations and one tri-μ-chlorido-tri-chlorido-μ-oxido-di-anti-monate(III) anion. The structure of the inorganic cation may be described as as being built up from two polyhedra, i.e. a square-pyramidal SbCl4O and a distorted octa-hedral SbOCl5 unit, sharing a common face (comprising the O atom and two Cl atoms). The two benzo-thia-zole cations are quasi-planar and subtend a dihedral angle of 19.93 (5)°. The crystal packing can be described by alternating (100) layers and [001] chains of the organic cations and inorganic anions connected through an extensive three-dimensional network of N-H⋯Cl, C-H⋯O and C-H⋯Cl hydrogen bonds. This is consolidated by slipped π-π stacking, with centroid-to-centroid distances between the benzo-thia-zole rings of 3.7111 (18)-3.8452 (16) Å. These inter-actions link the mol-ecules within the layers and also link the layers together and reinforce the cohesion of the ionic structure.

Tetra-kis(dihydrogen pefloxacinium) di-?(2)-chlorido-bis-[tetra-chloridobismuthate(III)] tetra-chloride octa-hydrate.

Project description:The title compound {systematic name: tetra-kis[4-(3-carb-oxy-1-ethyl-6-fluoro-4-hydroxonio-1,4-dihydro-7-quinol-yl)-1-meth-yl-piperazin-1-ium] di-?(2)-chlorido-bis-[tetra-chlorido-bismuth-ate(III)] tetra-chloride octa-hydrate}, (C(17)H(22)FN(3)O(3))(4)[Bi(2)Cl(10)]Cl(4)·8H(2)O, is composed of edge-shared centrosymmetric dinuclear [Bi(2)Cl(10)](4-) anions, Cl(-) anions, dihydrogen pefloxacinium cations and water mol-ecules. The Bi(III) coordination polyhedron is a distorted octa-hedron. There are four short terminal Bi-Cl bonds [2.5037?(10)-2.6911?(7)?Å] and two longer bridging bonds [2.8834?(8) and 3.0687?(9)?Å] in each octa-hedron. Two sets of chloride ions and water mol-ecules are disordered over the same sites with site occupancies of 1/3 and 2/3, respectively. Anions, cations and water mol-ecules are linked by O-H?O, O-H?Cl and N-H?Cl hydrogen bonds, forming a three-dimensional framework. There are also ?-? stacking inter-actions between quinoline ring systems [centroid-centroid distance = 3.575?(1)?Å].

Tri-?-chlorido-bis-[(?-hexa-methyl-benzene)-ruthenium(II)] tetra-chlorido-ferrate(III).

Project description:The mol-ecular geometry of the complex cation in the title structure, [(?-Cl)(3){Ru(II)(?(6)-C(6)Me(6))}(2)][Fe(III)Cl(4)], compares very well with that reported earlier for the corresponding PF(6) (-) salt [Pandey et al. (1999 ?). J. Organomet. Chem.592, 278-282]. The [FeCl(4)](-) counter ion has a rather regular tetra-hedral geometry with Fe-Cl distances and Cl-Fe-Cl angles in the range 2.1891?(7)-2.2018?(8)?Å and 107.10?(3)-110.56?(3)°, respectively. There are no significant inter-molecular inter-actions in the crystal except for some weak C-H?Cl contacts, which in turn indicates that the crystal packing is determined predominantly by electrostatic inter-actions between the ionic constituents.

Crystal structure of cis-bis-(μ-β-alanine-κ(2) O:O')bis[tri-chlorido-rhenium(III)](Re-Re) sesquihydrate.

Project description:The structure of the title compound, [Re2Cl6(C3H7NO2)2]·1.5H2O, comprises a dinuclear complex cation [Re-Re = 2.2494 (3) Å] involving cis-oriented double carboxyl-ate bridges, four equatorial chloride ions and two weakly bonded chloride ligands in the axial positions at the two rhenium(III) atoms. In the crystal, two complex mol-ecules and two water mol-ecules constitute hydrogen-bonded dimers, while an extensive hydrogen-bonding network involving the groups of the zwitterionic ligand is important for generation of the framework. An additional partially occupied water molecule is disordered over two sets of sites about a symmetry centre with a site-occupancy ratio of 0.3:0.2.

Crystal structure of di-?-chlorido-bis-[di-chlorido-bis-(methanol-?O)iridium(III)] dihydrate: a surprisingly simple chlorido-iridium(III) dinuclear complex with methanol ligands.

Project description:The reaction between IrCl3·xH2O in methanol led to the formation of small amounts of the title compound, [Ir2Cl6(CH3OH)4]·2H2O, which consists of two IrCl4O2 octa-hedra sharing an edge via chloride bridges. The mol-ecule lies across an inversion center. Each octa-hedron can be envisioned as being comprised of four chloride ligands in the equatorial plane with methanol ligands in the axial positions. A lattice water mol-ecule is strongly hydrogen-bonded to the coordinating methanol ligands and weak inter-actions with coordinating chloride ligands lead to the formation of a three-dimensional network. This is a surprising structure given that, while many reactions of iridium chloride hydrate are carried out in alcoholic solvents, especially methanol and ethanol, this is the first structure of a chloridoiridium compound with only methanol ligands.
