Abstract―: The composition and stability constants of homo- and heteroligand copper(II) complexes with benzoic acid, p-methoxybenzoic acid, or o-hydroxybenzoic acid hydrazide and L-histidine have been determined by spectrophotometry and mathematical modeling methods in aqueous solution with 0.1 M KNO3 as background at 25.0°C. Structural features of some complexes formed in binary and ternary systems have been determined using IR spectroscopy and quantum-chemical calculations.
