Abstract

The title compound, [Cu(2)(CH(3)CO(2))(4)(C(7)H(5)NS)(2)] or [(C(7)H(5)NS)Cu](2)(μ-O(2)CCH(3))(4), crystallizes with one mol-ecule 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) Å from these planes towards the N atoms. Thus, the Cu-Cu distance is elongated to 2.6378 (7) Å, compared with the 2.2180 (7) Å distance between the two basal planes. The angle between the basal plane and the Cu-N bond is 4.84 (6)°.
