Abstract

The complexation reaction between some transition and heavy metal cations and some new N₂O₂ Schiff bases in acetonitrile (AN) or methanol (MeOH) as nonaqueous solvents at 25 ^°C and 0.05 M tetraethylammonium perchlorate (TEAP) were investigated by spectrophotometric method. The stoichiometry and overall stability constants of complexes have been evaluated by computer refinement of abs-mole ratio data, using the KINFIT program. All investigated metal ions form 1:1 ML, 1:2 ML₂ or 2:1 M₂L complexes with studied ligands. The effect of structure on the complexation was investigated.
