Crystal structure of bis-(2-methyl-1H-imidazol-3-ium) ?-oxalato-bis-[n-butyl-tri-chlorido-stannate(IV)].

ABSTRACT: The Sn(IV) atom in the centrosymmetric anion of the title salt, (C4H7N2)2[Sn2(C4H9)2(C2O4)Cl6], is coordinated in a distorted octa-hedral mode by two O atoms of a bridging oxalate moiety, three Cl atoms and a C atom of an n-butyl group. The latter is disordered over two sets of sites in a 0.66:0.33 occupancy ratio. N-H?O and N-H?Cl hydrogen bonds involving the 2-methyl-imidazolium cation and neighbouring anions result in the formation of chains extending parallel to [001].

Crystal structure of 2-methyl-1H-imidazol-3-ium aqua-tri-chlorido-(oxalato-?(2) O,O')stannate(IV).

Project description:The tin(IV) atom in the complex anion of the title salt, (C4H7N2)[Sn(C2O4)Cl3(H2O)], is in a distorted octa-hedral coordination environment defined by three chlorido ligands, an oxygen atom from a water mol-ecule and two oxygen atoms from a chelating oxalate anion. The organic cation is linked through a bifurcated N-H?O hydrogen bond to the free oxygen atoms of the oxalate ligand of the complex [Sn(H2O)Cl3(C2O4)](-) anion. Neighbouring stannate(IV) anions are linked through O-H?O hydrogen bonds involving the water mol-ecule and the two non-coordinating oxalate oxygen atoms. In combination with additional N-H?Cl hydrogen bonds between cations and anions, a three-dimensional network is spanned.

Crystal structure of bis-(2-methyl-1H-imidazol-3-ium) di-hydroxidobis(oxalato-κ(2) O (1),O (2))stannate(IV) monohydrate.

Project description:In the structure of the hydrated title salt, (C4H7N2)2[Sn(C2O4)2(OH)2]·H2O, the asymmetric unit comprises one stannate(IV) dianion, two organic cations and one water mol-ecule of crystallization. The [Sn(C2O4)2(OH)2](2-) dianion consists of an Sn(IV) atom chelated by two oxalate anions and coordinated by two OH(-) ligands in a cis octa-hedral arrangement. Neighbouring anions are connected through O-H⋯O hydrogen bonds between hydroxide groups and non-coordinating oxalate O atoms into layers expanding parallel to (100). In addition, cations and anions are linked through N-H⋯O hydrogen bonds, and the water mol-ecule bridges two anions with two O-H⋯O hydrogen bonds and is also the acceptor of an N-H⋯O hydrogen bond with one of the cations. Weak C-H⋯O hydrogen bonds are also observed. The intricate hydrogen bonding leads to the formation of a three-dimensional network.

catena-Poly[2-methyl-1H-imidazol-3-ium [(aqua-chloridocadmate)-di-μ-chlorido]].

Project description:The asymmetric unit of the title compound, {(C(4)H(7)N(2))[CdCl(3)(H(2)O)]}(n), contains one 1-methyl-1H-imidazol-3-ium cation, one Cd(II) atom, three Cl atoms and one water mol-ecule. Adjacent Cd ions are inter-connected alternately by paired Cl(-) bridges to generate an infinite one-dimensional coordination chain along the b axis. In the chain, the crystallographically unique Cd(II) atom, with a distorted octa-hedral geometry, is coordinated by five Cl(-) ions and one water mol-ecule. Intra-chain O-H⋯Cl hydrogen bonding and N-H⋯Cl hydrogen bonding between the cations and the anionic chains consolidate the crystal packing.

Bis(cyclo-hexyl-ammonium) tetra-chlorido-(oxalato)stannate(IV).

Project description:The title salt, (C6H14N)2[Sn(C2O4)Cl4], was obtained as a by-product from the reaction between 2C6H14N(+)·C2O4 (2-)·1.5H2O and SnCl2·2H2O. The cyclo-hexyl-ammonium cation has a chair conformation. The complex anion consists of an oxalate anion chelating the SnCl4 moiety, resulting in a distorted octa-hedral coordination sphere of the Sn(IV) atom with the O atoms in equatorial cis positions. In the crystal, cations and anions are linked through N-H⋯O and N-H⋯Cl inter-actions into a layered arrangement parallel to (100).

Bis(5-amino-4-amino-carbonyl-1H-imid-azol-3-ium) (5-amino-4-amino-carbonyl-1H-imidazol-3-ium-κO)-di-μ-chlorido-hepta-chlorido-dibismuth(III) mono-hydrate.

Project description:The title compound, (C(4)H(7)N(4)O)(2)[Bi(2)Cl(9)(C(4)H(7)N(4)O)]·H(2)O, was prepared by the reaction of bis-muth trichloride and 5-amino-1H-imidazole-4-carboxamide in a dilute HCl medium. The asymmetric unit contains two 5-amino-4-amino-carbonyl-1H-imidazol-3-ium cations, one edge-shared non-centrosymmetric biocta-hedral [Bi(2)C1(9)(C(4)H(7)N(4)O)](2-) dianion and a water mol-ecule. In the dianion, the planar 5-amino-4-amino-carbonyl-1H-imidazol-3-ium ligand occupies an equatorial site and is inclined at an angle of 75.7 (2)° to the Bi(2)(μ-C1)(2) plane. The salt forms a three-dimensional network arising from hydrogen bonds between cations, anions and water mol-ecules.

Project description:The asymmetric unit of the title compound, (C4H7N2)2[CoCl4], consists of two 2-methyl-imidazolium cations and one tetra-hedral [CoCl4](2-) anion. The anions and cations inter-act through N-H⋯Cl hydrogen bonds to define layers with a stacking direction along [100]. Besides van der Waals forces, weak C-H⋯Cl inter-actions between these layers stabilize the crystal packing.

Crystal structure of di-chlorido-[2-(1H-imidazol-2-yl-?N (3))imidazolato-?N]bis-(tri-n-butyl-phosphane-?P)rhodium(III).

Project description:In the title compound, [Rh(C6H5N4)Cl2(C12H27P)2], the Rh(III) ion is chelated by the singly deprotonated 2,2'-biimidazolate (Hbim(-)) ligand and coordinated by two chloride ions and two tri-n-butyl-phosphane ligands. The chloride ions and N atoms of the Hbim(-) ligand lie in a plane where the sum of X-Rh-X angles between cis sites is 360°. The phosphane ligands occupy the sites perpendicular to the plane, completing the overall distorted octahedral coordination sphere. The complex forms a self-complementary hydrogen-bonded dimer with the inversion-related complex through N-H?N hydrogen bonds.

catena-Poly[[chloridocadmium(II)]bis-{μ-1-[(2-ethyl-1H-imidazol-1-yl)meth-yl]-1H-benzotriazole}[chloridocadmium(II)]di-μ-chlorido].

Project description:In the polymeric title complex, [CdCl(2)(C(12)H(13)N(5))](n), the Cd(II) atom is five-coordinated by two N atoms from two bridging 1-[(2-ethyl-1H-imidazol-1-yl)meth-yl]-1H-benzotriazole (bmei) ligands, two bridging Cl atoms and one terminal Cl atom in a distorted trigonal-bipyramidal geometry. The Cd(II) atoms are connected alternately by the Cl atoms and bmei ligands, leading to a zigzag chain extending parallel to [011]. π-π inter-actions, with a centroid-centroid distance of 3.3016 (3) Å, help to stabilize the crystal packing.
