Abstract
In the title complex, [Cd(C10H5O8)2(C10H9N5)2(H2O)2]·2H2O, the CdII ion lies on an inversion center and is coordinated by two N atoms from two symmetry-related 1-[(1H-benzimidazol-2-yl)methyl]-1H-1,2,4-triazole ligands and two O atoms from two monodeprotonated 2,4,5-tricarboxybenzoate anions in equatorial positions and by two water O atoms in axial positions, leading to a distorted octahedral environment. In the crystal, complex molecules and solvent water molecules are linked through intermolecular O—H⋯O, O—H⋯N and N—H⋯O hydrogen bonds into a three-dimensional network. Intramolecular O—H⋯O hydrogen bonds are also present.
