mixed-ligand platinum(II) complexes of the type [PtCl(DMSO)(L)], where HL=N,N-diethyl-N′-(3-R-benzoyl)thiourea, N,N-di(2-hydroxyethyl)-N′-(3-R-benzoyl)thiourea or N-morpholino-N′-(3-R-benzoyl)thiourea (R=H, Cl, NO2, CH3O, CH3), have been synthesised and characterised by elemental analysis, IR spectroscopy and 1H and 195Pt NMR spectroscopy. The spectroscopic data are consistent with the complexes containing
—A series of N-morpholine or N,N-diethyl, N'-substituted benzoylthioureas (R = Cl, Br, OMe or NO2 in ortho-, meta- or para-position) has been synthesized by condensation of morpholine or diethylamine with substituted benzoyl isothiocyanates. NMR spectra and magnetic measurements have shown square-planar NiL2 and fac-CoL3 complexes. The influence of the different substituents on the NMR and electronic
