Representative platinum(II) complexes of pyridil bis(N(4)-substituted thiosemicarbazones), in which the substituents replacing the NH2 of the thiosemicarbazone moieties are piperidyl, H2Plpip; hexamethyleneiminyl, H2Plhexim; diethylamino, H2Pl4DE; and dipropylamino, H2Pl4DP, have been synthesized and characterized with IR, electronic, mass, and 1H NMR spectra. Crystal structures have been solved for two platinum(II) complexes formed from H2Pl4DP. [Pt(Pl4DP)] has square-planar N2S2 coordination (i.e. imine nitrogen and thiolato sulfur atoms) and [Pt2(Pl4DP)Cl2] has two PtNNSCl centers with the pyridine nitrogen, imine nitrogen and thiolato sulfur atoms coordinated. |
