Crystal packing in a solvent-free or chloroform-solvated dinuclear platinum(III) organometallic complex

The synthesis and crystal structure determination of the dinuclear organometallic platinum(III) complex [Pt(2-phenylpyridine)(2-mercaptothiazoline)(Cl)]2 and its solvate [Pt(2-phenylpyridine)(2-mercaptothiazoline)(Cl)]2·3CHCl3 have been performed. Both crystals present a layered structure in which the molecules of the complex are held together by weak intermolecular interactions. In the solvated crystal, the chloroform molecules are arranged in extended 2D planar layers between the molecular layers.

► A platinum(III) cyclometallated complex can synthesized by in situ oxidation.
► Differing intermolecular interactions generate two very similar layered crystal structures.
► Chloroform solvent molecules cause molecular layer separation.
