Abstract: New series of co - ordination compounds of some transition metal ions [Zn (II), Ni (II), Cu (II) ] of synthesized ligand (4 - [2{5 - [4 - Nitrobenzylidene) - amino] - [1, 3, 4]thiadiazole - 2yl}phenylimino) - methyl] - phenol. These new prepared metal complexes and Schiff base ligand were characterised by elemental microanalysis (CHNSO), FTIR, UV - Vis, 1H - NMR, thermal analysis (TGA - DTA), magnetic susceptibility and molar conductance. Accordance to the obtained data all the prepared complexes were non - electrolytic. On the basis of the instrumental results, structures of metal complexes have been proposed. From the spectral data it is revealed that all prepared complexes exhibit 2: 1 (ligand: metal) ratio. Thermal data shows degradation of these complexes.
