Abstract: In this work, samples of cobalt (II, III) oxide nanoparticles stabilized with alkyldimethylbenzylammonium chloride were obtained by chemical precipitation in an aqueous medium. This material has a wide range of applications in electronics, agriculture, and medicine due to its magnetic, antibacterial, and conductive properties. Investigations were carried out using X-ray phase analysis, scanning electron microscopy, and infrared spectroscopy as well as quantum chemical modeling of the interaction of alkyldimethylbenzylammonium chloride and cobalt (II, III) oxide nanoparticles. During the study of the phase composition, it was found that the resulting sample has a cubic crystal lattice with a spatial face-centered group. Based on analysis of the microstructure, it was found that the sample was formed from irregularly shaped agglomerates ranging in size from 8 to 47 microns, consisting of spherical nanoparticles with a diameter from 50 to 75 nm. As a result of computer quantum chemical modeling, it was found that the interaction of cobalt (II, III) oxide nanoparticles with alkyldimethylbenzylammonium chloride is energetically favorable and chemically stable and occurs through nitrogen cation, which is confirmed by the results of infrared spectroscopy. Analysis of the obtained spectra showed that the interaction of cobalt (II, III) oxide with alkyldimethylbenzylammonium chloride occurs in the range of 1522-1630 cm-1 through the ionized amino group NH2+.
