ABSTRACT:

Six complexes of transition metals with 2 hydroxy 3 methoxy benzaldehyde (orthovanillin) thiosemicarbazone were synthesized and characterised by elemental analysis, (by CHNS Analyser and ICPAES) conductance and magnetic measurements, infrared and NMR spectral analysis and thermal analysis. Antibacterial activity tests, SHG measurements for non linear optical activity were made. Four complexes have the general formula [M(OVTSC)2X2 ] where M = Mn & Cd, OVTSC = Orthovanillin thiosemicarbazone. The copper complexes have the formula [Cu(IVTSC)X2 (H2O)2]. In all the complexes X = Cl,NO3. The presence of water in the copper complex is proved by thermal analysis. In all complexes the ligand co-ordinates to the metals bidendately.
