from precursor dimeric Pt(II) species via an intermediate DMSO adduct of the general form [PtCl(L1–4)(DMSO)]. Single crystal X-ray diffraction studies were undertaken on three complexes, [Pt(L1)(acac)], [PtCl(L1)(DMSO)], and [Pt(L1)(bpy)](PF6). The structures show that the complexes each adopt a distorted square planar geometry (most severely in the case of [Pt(L1)(bpy)](PF6)) with indications of intermolecular
