Abstract
Poteniometric studies of interaction between transition metal ions, Cu(II), Ni(II), Co(II), Zn(II) and Cd(II),
F-block ions UO2(VI), Th(IV) Sm(III) and Er(III) and mixed ligands are described. Benzyl-monohydrazone-3-
hydrazino-4-Benzyl-6-phenyl Pyridazine (BHP) used as primary ligand and 8-hydroxy quinolone (8-HQ), 2-Amino4-methyl pyridine (2-AMP) or 1,10-phenanthroline (1,10-Phen) used as secondary ligand. Mixed complexes are
formed in 75% (v/v) dioxane-water and 1:1:1 molar ratio of M+n to BHP as a primary ligand and 8-HQ, 2-AMP or
1,10-Phen as a secondary ligand. It was found that the order of stability constant for complexes of transition metal
ions runs according to:Cu(II) > Co(II) > Ni(II) > Cd(II) > Zn(II). While the order that obtained for F-block
complexes are runs according to: Th(IV) > UO2(VI) > Sm(III) > Er(III). Also, Ni(II), Co(II) and Cu(II) ternary
complex systems in solid states were isolated and characterized by different techniques
