Abstract

Reactions of first series transition-metal cations, Cd(II) and Al(III) with two aroylhydrazones derived from nicotinic acid hydrazide and salicylaldehide or o-vanillin were studied at 25 oC in buffered dioxane/water 1/1 mixture (pH = 5.8) by means of spectrophotometric and spectrofluorimetric titrations. The addition of Mn(II) or Cd(II) ions in hydrazone solutions had no effect on their absorption spectra whereas the addition of Ni(II) and Cr(III) immediately caused precipitation. The reaction of Zn(II) with salicylaldehide derivative was found to be photosensitive. Relatively high conditional stability constants of 1:1 complexes of Cu(II), Zn(II) and Al(III) with both ligands were determined. Solid complexes of Cu(II), Ni(II) and Zn(II) with aroylhydrazones studied were isolated and characterized by elemental and thermogravimetric analyses, magnetic susceptibility measurements (in the case of Cu(II) and Ni(II)) and IR spectrometry.
