Abstract
The reaction of benzoyl and salicoylhydrazones of vanilline, furfural, and cinnamaldehyde with some divalent metal ions of the first transition series is investigated. The structure of the ligand in the solid chelates is studied by IR-spectrophotometry which showed that the ligand is coordinated to the central metal ion through the oxygen atom of the C=O and nitrogen atom of the C=N group. Spectrophotometric, and conductometric studies were carried out to investigate the stoichiometry of the complexes under consideration. The shifts in the C=O and C=N IR-bands are utilised for the determination of the coordination bond length.
