Abstract
The title dinuclear platinum(III) complex, [Pt2(C11H8N)2(C5H4NS)4], forms two crystal structures, viz. the non-solvated and acetonitrile-solvated (C2H3N) forms. For both forms, two (2-pyridylphenyl)platinum units are bridged by two pyridine-2-thiolate (pyt) anions in a head-to-tail configuration, and the other two pyridine-2-thiolate anions occupy the axial position, coordinated through their S atoms. The most remarkable difference between the two forms is the orientation of the axial monodentate ligands. Those for the solvated form are located over the 2-pyridylphenyl ligands, being related by a twofold axis which lies through the centre of the Pt-Pt bond, while the axial pyt ligands for the non-solvated form are oriented irregularly, which is attributable to the dimeric arrangement in the crystal.
