trans-Bis(4-aminopyridine-κN)bis(quinoxaline-2,3-dithiolato-κ2S,S′)platinum(IV) dimethyl sulfoxide monosolvate

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-aminopyridyl, C5H6N2; qdt = quinoxaline-2,3-dithiolate, C8H4N2S2; dmso = dimethyl sulfoxide, C2H6OS) the centrosymmetric complex exhibits Pt—S distances in agreement with other PtIV—S bond lengths found in platinum(IV) dithiolene complexes. The qdt ligands have intermolecular interactions with an amine hydrogen atom on a 4-ap ligand (hydrogen bonding) and have sandwich π–π interactions with a neighboring qdt ligand.
