The synthesis and characterization ( elemental analysis, i.r.,u.v., magnetic measurements and cyclic voltammetry) of some new Co-II complexes with bidentate bulky salicylaldimines derived from 3,5-di-t-butylsalicylaldehyde and o- or p-substituted ( X = Cl, Me, OMe, Bu-t) aniline derivatives are reported in this paper. The presented ligands show very low complexation ability in respect of Ni-II, VOII, Mn-II, Zn-II and Cd-II metal ions. Electrochemical studies on the complexes, though revealing a dependence of the metal centered redox potentials on electronic and steric effects of the aniline substituents X, the potentials of the ligand-centered oxidation do not correlate with the electronic effects of X.
