title: 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.
