NMR and Other Physicochemical Studies of o-Vanillin and Isovanillin Salicyloylhydrazones and Their Metal Complexes
摘要:
Cobalt(II), nickel(II) and copper (II) complexes of (o) under bar-vanillin and isovanillin salicyloylhydrazones have been synthesised. These compounds were characterised by elemental analyses, IR, magnetic, thermal and diffuse reflectance spectra. The salicyloylhydrazones have been further characterised by H-1 NMR. Force constants of the major bonds, M-O and M-N have also been calculated.
