Аннотация
New coordination compounds of Co(II), Ni(II), and Cu(II) halides with 2-methyl-1,2,4-triazolo[1,5-a]benzimidazole (L), [Co(L)2Cl2] (Ia), [Ni(L)2(H2O)4]Cl2 · 4H2O (II), and [Сu2(L)4(µ-Br)2Br2] (IIIa), are synthesized. The complexes are studied by X-ray structure analysis (СIF files CCDC nos. 1825006–1825008), electronic (diffuse reflectance) spectroscopy, and IR spectroscopy. In compounds Ia, II, and IIIa, ligand L is coordinated to the metal by the N4 atom of the triazole fragment. The study of the cytotoxic effect of the ligand and synthesized complexes on the Hep-2 line (laryngeal cancer cells) shows a considerably higher activity of the copper(II) complex than that of the ligand.
