Aquatris(1H-benzimidazole-N³)(dichloroacetato-O)copper(II) dichloroacetate dihydrate

Y.-F. Li and F.-F. Jian

Abstract: The title compound, [Cu(C₂HCl₂O₂)(C₇H₆N₂)₃(H₂O)]C₂HCl₂O₂·2H₂O, 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-HO and N-HO hydrogen bonds. The Cl atoms are disordered over two sites, with relative occupancies 0.67 (3) and 0.33 (3).
