На основании данных масс-спектрометрии и ИК-спектроскопии показано, что в результате электролиза прошло формирование как тетракетонатного лиганда, так и квазиароматического металлоцикла – основного структурного элемента хелата. Периферийные группы (трифторметил и теноил) тетракетонатного лиганда не подверглись трансформации под воздействием электрического тока. Полученное хелатное соединение самария является перспективным прекурсором для синтеза светодиодных и активных лазерных сред оранжевого свечения.</p></abstract><trans-abstract xml:lang="en"><p>Samarium (III) 1,1,1,6,6,6-hexafluoro-3,4-di(2-thiophenemethanone) hexanedionate-2,5 was obtained from thenoyltrifluoroacetone by electrochemical synthesis. Mass spectrometry and IR spectroscopy data showed that electrolysis resulted in the formation of both the tetraketonate ligand and the quasi-aromatic metallocycle, the main structural element of the chelate. The peripheral groups (trifluoromethyl and thenoyl) of the tetraketonate ligand were not transformed by the electric current. The resulting samarium chelate compound is a promising precursor for the synthesis of orange-emitting light-emitting diodes and active laser media.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>хелат</kwd><kwd>теноилтрифторацетон</kwd><kwd>самарий</kwd><kwd>ИКи масс-спектры</kwd></kwd-group><kwd-group xml:lang="en"><kwd>chelate</kwd><kwd>thenoyltrifluoroacetone</kwd><kwd>samarium</kwd><kwd>IR and mass spectra</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Работа выполнена в рамках ГПНИ «Фотоника, оптои микроэлектроника» (ГР № 20191450) и ГПНИ «Фотоника и электроника для инноваций» (ГР № 20211794)</funding-statement><funding-statement xml:lang="en">This work was supported by the State Program for Scientific Research “Photonics, Optoand Microelectronics” (State Program for Scientific Research No. 20191450) and the State Program for Scientific Research “Photonics and Electronics for Innovations” (State Program for Scientific Research No. 20211794)</funding-statement></funding-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Binnemans, K.
