Abstract
A new hydrazone Schiff base ligand namely caprylaldehyde isonicotinoyl hydrazone (CINH) has been synthesised and characterised by H-1-NMR and electronic elemental analysis, IR, spectroscopy. The signal due to az omethinic proton H-C=N is observed at 8.50 ppm. Several bipositive met al ions were employed to form complexes. Thermal degradation of the co mplexes has been examined up to 1000 degrees C and the force constants of M-O and M-N bonds evaluated. The mode of complexation in enolic fo rm of the ligand in 4-coordinated complexes has been discussed.
