The article presents the results of our research on the synthesis of pyridine-containing coordination polymers based on zinc and copper. At the moment, metal-organic coordination polymers are considered one of the most interesting and rapidly developing areas of organic chemistry. This determines their use in petrochemistry, pharmaceuticals, construction and much more. The introduction presents a literature review on the methods of synthesis of metal-organic coordination polymers, their structure and the main pyridine ligands used. The structure of a known polymer based on pyridine-3,5-dicarboxylic acid and europium is presented. The materials and methods describe the reagents used and the synthesis techniques. The discussion results present data on the obtained metal-organic polymers based on pyridine-2,6-dicarboxylic acid, and provide photographs of the polymer crystals obtained using a light microscope. The absorption spectra of the synthesized polymers were recorded in comparison with pyridine-2,6-dicarboxylic acid. It was shown that the absorption spectra of the initial acid and the obtained polymers exhibit a hypochromic effect of the carboxyl group signal, indicating the formation of a polymer. The polymer obtained on the basis of copper has a more ordered structure, gives a higher yield of the product and better strength properties in contrast to the zinc polymer. Key words: metal-organic polymers, pyridine, solvent evaporation, dicarboxylic acid, ligand.
