摘要：

The processes of formation of iron(II) complexes in aqueous glycine solutions in the pH range of 1.0-8.0 at 298 K and ionic strength of 1 mol/L (NaClO4) are studied using Clark and Nikolskii's oxidation potential method. The type and number of coordinated ligands, the nuclearity, and the total composition of the resulting complexes are determined. The following complex species are formed in the investigated system: [Fe(OH)(H2O)(5)](+), [FeHL(H2O)(5)](2+), [Fe(HL)(OH)(H2O)(4)](+), [Fe(OH)(2)(H2O)(4)](0), [Fe-2(HL)(2)(OH)(2)(H2O)(8)](2+), and [Fe(HL)(2)(H2O)(4)](2+). Their formation constants are calculated by the successive iterations method using Yusupov's theoretical and experimental oxidation function. The model parameters of the resulting coordination compounds are determined.
