Abstract
Mixed-ligand complexes of Co(II) and Cu(II) with rutin and glycine were synthesized and studied by the method of "block" synthesis. The composition and structure of the synthesized compounds in solutions and in the solid state were studied, and their spectral and luminescent properties were determined. It is shown that the mixed-ligand complexes have the composition MII(Gly)2(Rut), while the coordination of 3-d metal ions occurs through the catechol fragment of rutin and the carboxyl and amino groups of two glycine molecules. For complexes in solutions, luminescence was detected in the visible region of the spectrum (~500–540 nm). It is shown that 3-d metal ions quench the luminescence of rutin, but in the presence of glycinate ion, the luminescence intensity of the complexes increases. The antibacterial activity of the complexes against pathological bacteria Escherichia coli, Klebsiella pneumoniae, Staphylococcus aureus, P. Aeruginosa was studied. It has been shown that the synthesized compounds have an antimicrobial effect.
