For the first time, mixed-ligand complex compounds of Co(II) with 2-amino-1-methylbenzimidazole (MAB) and salicylic acid (SA) were synthesized. The structures of the synthesized complexes were investigated using elemental analysis, SEM-EDS, IR and Raman spectroscopy, as well as thermogravimetric analysis. The results showed that the complexes' composition, structural features, and physicochemical properties are influenced by both the type of complexing agent involved and the specific coordination behavior of the ligands.
