A new copper(II) complex, [Cu(BMI)4(SO4)]·DMF·2H2O (BMI = benzimida- zole), has been synthesized by the treatment of CuCN with 2-mercaptobenzimidazole in the presence of 1,10-phenanthroline, and characterized by single-crystal X-ray diffraction. It crystalli- zes in monoclinic, space group P21/n with a = 17.6260(4), b = 11.1252(3), c = 18.6573(4)(A),β = 107.9010(10)°, V = 3481.45(14)(A)3, Z = 4, C31H35CuN9O7S, Mr = 741.28, F(000) = 1540, Dc = 1.414 g/cm3, μ = 0.746 mm-1, the final R = 0.0649 and wR = 0.1609 for 4382 observed reflections with I > 2σ(I). The Cu(II) atom is coordinated by five unidentate ligands (one sulfate and four benzimidazole ligands) generated in situ, displaying a slightly distorted square pyramid geometry.
