Abstract

In the structure of the title solvated complex, [Pt(C₈H₄N₂S₂)₂(C₅H₆N₂)₂]·C₂H₆OS or trans-[Pt(4-ap)₂(qdt)₂]·dmso (4-ap = 4-amino-pyridyl, C₅H₆N₂; qdt = quinoxaline-2,3-di-thiol-ate, C₈H₄N₂S₂; dmso = dimethyl sulfoxide, C₂H₆OS) the centrosymmetric complex exhibits Pt-S distances in agreement with other Pt^IV-S bond lengths found in platinum(IV) di-thiol-ene complexes. The qdt ligands have inter-molecular inter-actions with an amine hydrogen atom on a 4-ap ligand (hydrogen bonding) and have sandwich π-π inter-actions with a neighboring qdt ligand.

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