The aim of this work is to study the effect of the nature of electron-donor and electron-withdrawing substituents in the molecules of heterocyclic ligands, the nature of acidoligands and transition metal ions on the properties of the synthesized coordination compounds. A method for the synthesis of new complex compounds of Mn (II), Cо (II), Cu (II) and Zn with 5-amino-2-mercaptobenzimidazole has been developed and the composition and structure of the synthesized complex compounds have been studied using modern physicochemical methods, such as elemental, thermogravimetric, X-ray phase analysis and IR spectroscopy. Coordination competing donor centers, electronic and geometric structures of the ligand molecule were studied using quantum-chemical calculations in the Gaussian09 LanL2DZ software package. It was shown that during the formation of a metal complex, the ligand 5-amino-2-mercaptobenzimidazole is coordinated through the localized nitrogen atom of the imidazole ring.
