Abstract


Complexes of Mn(II), Zn(II) and Cd(II) with 2,5Dihydroxy butyrophenone thiosemicarbazone(L1)/2,5 Dihydroxy benzophenone thiosemicarbazone(L1) as primary ligands and 2,2'bipyridyl(L2) as secondary ligand have been isolated and characterized by elemental analysis, molar conductance, magnetic measurements, electronic spectra, IR spectra and thermogravimetric analysis. Conductivity data of the complexes in DMSO suggested their non?electrolytic nature. The molecular weight of the complexes determined by the Rast Camphor method corresponds with the weight of the formula, indicating their monomer nature. TG analysis confirms the presence of one coordinated water molecule in all the complexes. On the basis of above observations the complexes are proposed to be octahedral in nature.
