Tetra-μ-acetato-bis[(1,3-benzothiazole)-copper(II)](Cu-Cu)

The title compound, [Cu-2(CH3CO2)(4)(C7H5NS)(2)] or [(C7H5NS)Cu](2)(mu-O2CCH3)(4), crystallizes with one molecule per unit cell. The coordination number of copper is six with four basal O atoms, one axial N atom and one axial Cu atom. Four acetate ligands act as bidentate linker and connect two Cu atoms, with a crystallographic inversion center located at the mid-point of the Cu-Cu bond. The acetate ligands form slightly distorted square planes around each metal ion, while the copper ions are displaced by 0.2089 (4) angstrom from these planes towards the N atoms. Thus, the Cu-Cu distance is elongated to 2.6378 (7) angstrom, compared with the 2.2180 (7) angstrom distance between the two basal planes. The angle between the basal plane and the Cu-N bond is 4.84 (6)degrees.
