A Schiff base derived from 1-propyl 2-6-diphenyl piperidone thiosemicarbazone (PDPT) and its Co(II), Ni(II) and Cu(II) transition metal complexes were synthesized. Structure of the ligand and its complexes were derived on the basis of various physicochemical techniques such as molar mass, elemental analyses, Infrared spectra, electronic spectra, magnetic susceptibility and molar conductivity. On the basis of these observations, it has been observed that the ligand PDPT, coordinate to the metal ion in a bidentate fashion through the nitrogen and sulphur atom of thiosemicarbazone moiety. The remaining co-ordination centres are satisfied by anions such as Cl^-, Br^-, and I^-. Electronic spectra and magnetic susceptibility measurements reveal octahedral geometry for the Co(II) and Ni(II) ions where  distorted octahedral geometry for Cu(II) complexes. The complexes were found to be non-electrolytic in nature on the basis of low value of molar conductance.
