Abstract


Salicyaldehyde thiosemicarbazone complexes of Pd(II), Cu(II) and Ru(III) have been characterized by elemental analyses, molar conductance, infrared, NMR, electronic spectra and thermal analyses. The data show the formation of two different types of complexes 1:1 and 1:2 metal: ligand stoichiometries. The dc electrical conductivity of the ligand and the complexes was measured at varying temperatures. The results obtained were explained and discussed in terms of proposed semicondutive behavior of the complexes and a probable occurrence of phase transition. The activation energies were calculated for the ligand and the complexes.
