It crystallizes in the monoclinic system, space group P21/n with a = 14.7558(17), b = 20.770(2), c = 20.3260(19) A, β = 90.6110(10)°, V= 6229.2(11) A3 and Z = 8. The Cu atom is surrounded by two O atoms and two N atoms from two 2-[(2,4-diehloro-phenylimino)-methyl]-4,6-diiodo-phenol molecules to form a tetrahedral coordination environment.
