Displacement of cod from [Pt(cod)Cl2] by 2 equiv. of heteroarylphosphorus ligand, PR2R', in dichloromethane at ambient temperature afforded - but for one exception trans-[Pt(P{2-(N-methylpyrrolyl)}(i)Pr2)2Cl2] (1) - the expected cis complexes, cis-[Pt(P{2-(N-methylpyrrolyl)}Ph2)2Cl2] (2), cis-[Pt(P{2-(5-methylthienyl)}R2)2Cl2] (R = Ph 3, (i)Pr 4) and cis-[Pt(P{2-(5-bromopyridinyl)}(i)Pr2)2Cl2] (5). The complexes were fully characterised and structural assignments were based on 1J(195Pt-31P) coupling constants from the NMR data. The structure of 1 was determined by X-ray crystallography, which revealed that the two pyrrolyl substituents on the phosphine ligands were oriented on opposite sides of the P-Pt-P axis.
