Optimal synthesis conditions were developed and heterometallic coordination compounds of potassium acetate with cobalt(II), nickel(II), and copper(II) formats were synthesized. The yield of reaction products and the physical properties of the synthesized compounds were determined. Elemental analysis of the obtained compounds was carried out on an energy-dispersive scanning electron microscope. The identity of the received data with the calculated ones was established. According to the results of SEM-EDA, numerous peaks for metal ions were established, as well as the microscopic structure of the synthesized compounds. The degree of crystallinity of the new complexes was also determined. Based on elemental analysis, the empirical formula of the synthesized compounds was calculated. The study of the IR spectra of the synthesized compounds shows bidentate-bridging coordination of acetate ions with metals during the interaction of metal formates with potassium acetate. The energy and geometric properties of molecules are calculated by quantum-chemical calculation methods, and bond lengths and angular parameters are determined.

Keywords: scanning electron microscope and energy dispersion analysis (SEM-EDA), IR spectroscopy, elemental analysis, thermal analysis, diffuse reflection electron spectroscopy (DRES).
