چکیده
The title compound, [Ag(C(9)H(5)N(2)O(4))(C(9)H(6)N(2)O(4))]·H(2)O, contains one independent Ag atom, a neutral 1H-benzimidazole-5,6-dicarboxylic acid (bdcH), its monodeprotonated form, i.e. 5-carboxyl-ato-1H-1,3-benzimidazole-6-carboxylic acid (bdc), and one solvent water mol-ecule, the latter being disordered over three sites with site occupancy factors of 0.375 (× 2) and 0.25. In addition, the H atom on one carboxylic acid residue is disordered, being connected to each of the O atoms 50% of the time. The Ag atom is in a virtually linear geometry defined by two N atoms derived from the bdc and bdcH ligands. The three-dimensional supra-molecular structure is stablized by extensive O-H⋯O and N-H⋯O hydrogen bonds. An intramolecular O-H⋯O hydrogen bond is also present.
