Diaqua­bis­{1-[(1H-benzimidazol-2-yl)meth­yl]-1H-1,2,4-triazole-κN (4)}bis­(2,4,5-tricarb­oxy­benzoato-κO (1))cadmium dihydrate

In the title complex, [Cd(C(10)H(5)O(8))(2)(C(10)H(9)N(5))(2)(H(2)O)(2)]·2H(2)O, the Cd(II) 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.
