Özet

In the title compound, [Cu(C2H8N2)(2)](C12H6N2O4S2)center dot 1.5H(2)O, there are two half-molecules of the cationic complex in the asymmetric unit. The Cu2+ ions lie on inversion centres and are octahedrally coordinated by two ethylenediamine (en) and two aqua ligands in a typical Jahn-Teller distorted environment with the water O atoms in the axial positions. Two 2-mercaptonicotinate units (mnic) are linked by a disulfide bridge. All the ethylenediamine N-H and O-H groups form intermolecular hydrogen bonds with acceptor O and N atoms, giving rise to a three-dimensional network. One of the uncoordinated water molecules has a site occupation factor of 0.5.
