ABSTRACT:
The formation and stability of Pyridoxal semicarbazone (PLSC) and Pyridoxal thiosemicarbazone (PLTSC) Schiff base ligand (L) complexes of Co(II), Ni(II), Cu(II) and Zn(II) have been investigated by Irving-Rossotti pH-metric titration technique, at 30 ± 1ºC and an ionic strength of 0.1M KNO3 in 70% v/v DMF-H2O medium. The acid dissociation constants (pKa) of the ligands and the stability constants of the metal complexes formed in solution were determined. The results indicate the formation of 1:1(ML) and 1:2(ML2) complexes in solution. The order of stability of the metal complexes with respect to the metal ions follows the Irwing - william’s natural order, Co(II) ? Ni(II) ? Cu(II) > Zn(II).
