Stability Constants of Mixed Ligand Complexes of Transition Metal(II) Ions with 1-[(1E)-N-(2,6-Dichlorophenyl) Ethanimidoyl]Naphthalen-2-Ol and 4-Bromo-2-{(E)-[(2,3-Dimethylphenyl)Imino]Methyl}Phenol

Binary and ternary complexes of the type M-Y and M-X-Y [M=Co(II), Ni(II), Cu(II) and Zn(II); X=4-bromo-2-{(E)-[(2,3-dimethylphenyl)imino]methyl}phenol and Y=1-[(1E)-N-(2,6-dichlorophenyl)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.
