Annotation: A method for the synthesis of new mixed-metal complex compounds Mn (II), Co (II), Cu (II) and Zn with ammonium vanadate and 5-amino-2-mercaptobenzimidazole was developed and the composition and structure of the synthesized complex compounds were studied using modern physicochemical methods, as elemental, thermogravimetric analysis and IR spectroscopy. It was found that the ligand 5-amino-2-mercaptobenzimidazole is coordinated by the nitrogen atom in the imidazole ring in complexation reactions.

Keywords: ligand, 5-amino-2-mercaptobenzimidazole, complex compound, IR spectroscopy, elemental analysis, thermogravimetric analysis, composition, structure, properties.
