Formation constants ofMn(II) complexes with 5-nitro-, 5-chloro-, 5-methyl-, 4-methyl-, 2,9-dimethyl-, 4,7-dimethyl- and 5,6-dimethyl-1,10-phenanthroline and formal potentials of Mn(III)/Mn(II) couple in the presence of these compounds by use of potentiometric method were determined and used to calculate formation constants of Mn(III) complexeswith these ligands.Anumerical method of manganese(III) complexes formation constants calculation from potentiometric and voltammetric data was proposed and tested for iron(III) complexes. The influence of substituents on protonation and stability constant values was analyzed taking into account suitability of the ligand to stabilize thermodynamically unstableMn(III) ion and protect it from disproportionation.
