trans -Diamminebis(1,2-di-cyano-ethene-1,2-di-thiol-ato)platinum(IV).

The title compound, [Pt(C 4 N 2 S 2 ) 2 (NH 3 ) 2 ], represents an octa-hedral platinum(IV) complex with two trans- ammine and two mnt (mnt = 1,2-di-cyano-ethene-1,2-di-thiol-ato) ligands. The Pt-N and Pt-S distances are consistent with those in other platinum(IV) complexes. As a result of a slight canting of the coordination of the mnt ligand to the platinum(IV) atom, the nitrile nitro-gen atoms are positioned suitably to hydrogen-bond with adjacent ammines.
