Bis{N-[5-(4-methoxy-phen-yl)-1,3,4-oxa-diazol-2-yl]ethanimidamidato}copper(II).

The title compound, [Cu(C(11)H(11)N(4)O(2))(2)], was prepared by solvothermal synthesis using 2-amino-5-(4-methoxy-phen-yl)-1,3,4-oxadiazole and copper sulfate penta-hydrate in an acetonitrile solution. The Cu(II) atom lies on an inversion center and is four-coordinated in a slightly distorted square-planar geometry by four N atoms of the ligands obtained from the formation of a bond between the amine N atom of the oxadiazole mol-ecule and the nitrile C atom of the solvent. In the crystal structure an inter-molecular N-H⋯N hydrogen bond links inversion-related mol-ecules.
