ABSTRACT:

3-(4' – Pyridyl)-4-phenyl-triazoline-5-thione(PPytTH) forms stable coloured solid and acts as monodentate with Mn(II) and bidentate (N, S) with Co(II), Ni(II), Cu(II), Fe(III) and Ti(III) ions. The nature of shifts and change in intensity of all four thioamide bands of the ligand are used as diagnostic for metal-ligand bonding. Crystal field parameters in electronic spectra and metal-ligand vibrations in far-ir spectra of complexes have been tentatively assigned.
