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. |
