Abstract

Salicylhydroxamic acid and its binary and ternary copper(II), nickel(II), and iron(III) complexes involving 1,10-phenanthroline were studied pH-potentiometrically in 0.15 mol.L-1 NaNO3 aqueous solutions at 37 oC. The protonation constants of salicylhydroxamic acid and 1,10-phenanthroline as well their binary and mixed ligand complex species stability constants were determined based on 3 estimation models (Irving Rossetti, Bjerrum-Calvin and Hyperquad 2008). Also, six solid complexes were synthesized and their biological activities were evaluated against some pathogenic bacteria and fungi organisms.
