trans-Bis(ethyl­enediamine-κ²N,N′)bis­(6-methyl-2,2,4-trioxo-3,4-dihydro-1,2λ⁶,3-oxathia­zin-3-ido-κN)copper(II)

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—H...O hydrogen bonds. In the crystal, mol­ecules are connected by inter­molecular N—H...O hydrogen bonds into chains running along the a axis.
