SYNTHESIS AND APPLICATION OF ACETYL ACETONATE COMPLEXES OF TRIVALENT RHENIUM (RE(III)) WITH METAL-METAL COMPOUNDS

Abstract

Dinuclear acetylacetone derivatives of trivalent rhenium were obtained and their physicochemical and thermal properties were studied in detail. The composition and type of compounds were determined using chemical, IR-spectral and X-ray phase methods from various analytical methods. During the study of the proposed structures of the obtained compounds by IR spectral analysis, it was determined that the absorption spectra of ion complexes containing protonated amines are almost identical to each other. It was determined that there are intense bands at 1380 and 1460 cm-1, which are characteristic of symmetric and asymmetric bending vibrations of methyl groups, respectively. In addition, in the high-frequency region of the spectra, the presence of broad intense bands in the region of 3050-3250 cm-1 with several maxima characteristic of stretching vibrations of protonated amines was revealed. Thermogravimetric methods have determined that they decompose at low temperatures and that in all cases the final solid phase product is rhenium metal. As a result of many interesting studies, it was determined that many representatives of this class of compounds can be used as starting products for the production of effective catalysts in obtaining oxide or metal coatings and in many organic synthesis processes.
