A series of platinum (II) complexes of formulae cis-[Pt (Am) 2X2](where Am represents an inert amine and X a labile (carboxylato) ligand) have been prepared and characterized by elemental analysis, ESI-MS, IR and 1H NMR spectroscopy. The single-crystal molecular structures were determined for cis-[Pt (opea)(cbdca-2H)], cis-[Pt (hmpy)(cbdca-2H)], cis-[Pt (NH3) 2 (bzmal-2H)] and cis-[Pt (hmpy)(μ-dcch-2H) 2](where opea is picolylamine, hmpy ...
