Abstract

Binary and ternary complexes of the type M-Y and M-X-Y [M = Co(II), Ni(II), Cu(II) and Zn(II); X = 2-{(E)-[(2, 3-dimethylphenyl)imino]methyl}phenol and Y = 1-[(1E)-N-(4-methoxy-2-methylphenyl)ethanimidoyl]naphthalen-2-ol] have been examined pH-metrically at 27 ± 0.5°C and at constant ionic strength, μ = 0.1 M (KCl) in 75: 25 (v/v) 1, 4-dioxne-water medium. The stability constants for Binary (M-Y) and ternary (M-X-Y) systems were calculated.
