The thiosemicarbazone derivatives R-1-C6H4-CH=N-N=(C-S-R-2)-NH-R-3 [R-1 = H, OH; R-2 = H, Ph; R-3 = C2H5, C3H5] were prepared by a modified general method. The Pd(II) complexes of the thiosemicarbazone ligands LI-VIsupercript stop were isolated in the compositions [Pd(L)Cl-2], [Pd(L)Cl] and [Pd(L)(2)]. The 1: 1 and 1: 2 metal complexes have non-ionic character, and the compounds were characterized by analytical data and infrared and proton resonance spectroscopy. The cis-trans and syn-anti isomers of the thiosemicarbazones were determined by means of1supercript stopH NMR, and the coordination behavior of the polydentate thiosemicarbazone ligands towards the palladium ion were discussed.
