The formation reactions of hydrophobic metal complexes of divalent typical element and transition metal ions with a novel chelating ligand containing N and O donor atoms, 4,5-bis(diphenylphosphinoyl)-1,2,3-triazole (L(T)H), were investigated by the liquid-liquid distribution method carried out on metal ions between chloroform and aqueous solutions. The liquid-liquid distribution reaction formulae of metal ions via the formation of hydrophobic metal complexes were revealed, along with their equilibrium constants. Three types of hydrophobic mononuclear and binuclear metal complexes distributed into chloroform solutions were found, namely, ML(2) (M = Mg(2+), Zn(2+), Pb(2+); L = L(T)), ML(2)(HL) (M = Cd(2+), Mn(2+)), and M(2)L(3)(OH) (M = Co(2+), Ni(2+), Cu(2+)). Linear free energy relationships were found between the equilibrium constants of the liquid-liquid distribution reactions and the stability constants of 1: 1 complexes consisting of a divalent metal ion and a glycinate. These relationships suggest the chelate formation of N,O-coordination with a heterocyclic five-membered ring in the metal complexes with LTH. (C) 2009 Elsevier B. V. All rights reserved.
