Abstract

The title compound, [Pt(C₄N₂S₂)₂(NH₃)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.

Keywords: crystal structure; dithiolene; platinum(IV).
