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 Cu^II ion and the N atoms are considerably longer than the equatorial bond distances between the Cu^II 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-HO hydrogen bonds. In the crystal, molecules are connected by intermolecular N-HO hydrogen bonds into chains running along the a axis.
