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.

ABSTRACT: 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.

2,2'-(Imino-dimethyl-ene)dibenz-imid-azol-ium bis-(perchlorate) methanol solvate.

Project description:In the title compound, C(16)H(17)N(5) (2+)·2ClO(4) (-)·CH(3)OH, the dihedral angle between the two benzimidazolium ring systems is 34.6?(1)°. The anions and solvent mol-ecules are linked to the cation by N-H?O hydrogen bonds. In the crystal structure, the combination of N-H?O and O-H?O hydrogen bonds results in two-dimensional layers running parallel to the (010) plane; these are in turn linked by ?-? inter-actions, forming 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.

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.

Project description:The title solvated salt, C29H41N2 (+)·Br(-)·2CH2Cl2 was obtained from the reaction of the Arduengo-type carbene 1,3-bis-(2,6-diiso-propyl-phen-yl)-1,3-dihydro-4,5-dimethyl-2H-imidazol-2-ylidene with Si2Br6 in di-chloro-methane. The complete cation is generated by a crystallographic mirror plane and the dihedral angle between the five-membered ring and the benzene ring is 89.8?(6)°; the dihedral angle between the benzene rings is 40.7?(2)°. The anion also lies on the mirror plane and both di-chloro-methane mol-ecules are disordered across the mirror plane over two equally occupied orientations. In the crystal, the cations are linked to the anions via C-H?Br hydrogen bonds.

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.
