The acid-base properties of acetyl-and heptoylhydrazones of substituted salicylaldehyde derivatives and the stability of their copper(II) complexes have been studied. For both sets of compounds, the ionization constants of the hydrazones and the stability constants of hydrazone complexes are linear functions of the substituent constants sigma. An analogous tendency is found for the antiferromagnetic exchange interaction parameters in dimeric copper(II) nitrate complexes of heptoylhydrazones of substituted salicylaldehyde derivatives. A correlation between the protolytic properties of hydrazones and the magnetic properties of their complexes is suggested.
