Stability Constants of Mixed Ligand Complexes of Co (II), Ni (II), Cu (II) And Zn (II) Ions with 2-[(1E)-N-(4-Chlorophenyl) Ethanimidoyl] Naphthalen-1-ol and 2 - {(E)- [(2,3-Dimethyl Phenyl) Imino] Methyl} Phenol

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=2-[(1E)-N-(4 chlorophenyl) ethanimidoyl] naphthalen-1-ol] have been examined pH-metrically at 27 ± 0.5 oC 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.
