A new hydration Schiff base consisting of 7-chloro-4-(o-hydroxy benzilidenehydrazo) quinoline, with metal complexes of some divalent metal ions, Mn(II), Fe(III), Co(II), Ni(II), Cu(II), Zn(II), and Cd(II) complexes were studies. Spectrophotometrically obeyed Beer's law up to certain values, 6.6×103, 8.0×103dm3mol-1cm-1, respectively, indicating that the ligand HL could be used to detect Co(II) and Ni(II) in such concentrations, the study was performed also for Fe (III)-complexes. Conductance and thermodynamically used molar ratio method to determine the stoichiometry of the complexes obtained confirmed the formation of 1:1 and 1:2, M:L complexes. The standard thermodynamic parameters viz. ΔG, ΔH and ΔS, for the proton-legend and the stepwise metal-ligand complexes eluated were analyzed in terms of the electrostatic (eel) and non-electrostatic (crates, c) compo.. View More»
