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.
