Aqua­tris(1H-benzimidazole-κN (3))(dichloro­acetato-κO)copper(II) dichloro­acetate dihydrate

The title compound, [Cu(C(2)HCl(2)O(2))(C(7)H(6)N(2))(3)(H(2)O)]C(2)HCl(2)O(2)·2H(2)O, was prepared by reaction of copper(II) 2,2-dichloro­acetic acid and benzimidazole in ethanol solution. The compound shows a regular trigonal–bipyramidal stereochemistry. The Cu(II) centre possesses a five-coordinated environment, coordinated by three N atoms from the three benzimidazole ligands and two O atoms, one from the dichloro­acetate ligand and the other from the coordinated water mol­ecule. The mol­ecular structure and packing are stabilized by O—H⋯O and N—H⋯O hydrogen bonds. The Cl atoms are disordered over two sites, with relative occupancies 0.67 (3) and 0.33 (3).
