Mono-and dinuclear complexes of the type M (cys), M (PTD) 2 and M2 (PTD) 4, where M= Pd (II) or Pt (II), cys=(SCH 2CH (NH 2) COOH) 2 and PTD= pyrrolidine thiocarbanoyl disulfide, have been prepared through oxidative addition reaction. They are characterized by microanalyses of metal content, molar conductance, magnetic measurements, infrared and UV–visible spectral studies. The experimental infrared data are supported by density ...
