Abstract: In the crystal structure of the title compound, [Cu(C4H4NO4S)2(C2H8N2)2], the Cu2+ ion resides on a centre of symmetry. The environment of Cu2+ ion is a distorted octahedron. The axial bond lengths between the CuII ion and the N atoms are considerably longer than the equatorial bond distances between the CuII ion and the N atoms of the ethylenediamine ligand as a consequence of the Jahn-Teller effect. The molecular conformation is stabilized by intramolecular N-H...O hydrogen bonds. In the crystal, molecules are connected by intermolecular N-H...O hydrogen bonds into chains running along the a axis.
