It was prepared by reacting etioporphyrin II and bismuth(III) iodide in pyridine in Ar atmosphere. The prepared compound was characterized by FT-IR, 1H-NMR, UV-VIS spectroscopy and mass spectrometry. One intense line at m/z 684.990 attributed to the complex without the iodine atom is observed in the mass spectrum. This is in agreement with the data indicating that bismuthporphyrin complexes generally have low stability. Analysis of FT-IR spectra obtained at room temperature and at 145°С is reported. Priroda15 DFT package was used for optimization of complex geometry and calculation of the IR spectrum. Calculations were done using BPE functional and L1 basis set under relativistic approximation of Dyall Modified Dirac. Assignment of the vibrational frequencies is reported. Collected data indicate that the complex of bismuth(III) with iodine and etioporphyrin II is not stable and easily hydrolyses when exposed to air forming the corresponding hydroxocomplex. This transformation does not change significantly the dynamics of the porphyrin ring.</p></abstract><trans-abstract xml:lang="ru"><p>Впервые получен комплекс висмут(III) йод этиопорфирин II. Реакция этиопорфирина II с йодидом висмута(III) проведена при кипячении в пиридине в токе аргона. Соединение охарактеризовано методами ИК-, 1Н-ЯМР-, электронной спектроскопии и масс-спектрометрии. Масс-спектр представлен одной интенсивной линией m/z 684.990, соответствующей комплексному иону без атома йода. Последнее согласуется с данными, свидетельствующими о низкой устойчивости комплексов висмута с порфиринами. Выполнен анализ ИК-спектров поглощения полученного комплекса при комнатной температуре и 145°С. Оптимизация геометрии и расчет частот поглощения выполнены в программе Priroda15 методом DFT с использованием функционала PBE в базисе L1 в полноэлектронном скалярно-релятивистском приближении Dyall Modified Dirac. Проведено отнесение колебательных частот. Полученные результаты позволяют заключить, что комплекс висмут(III) йод этиопорфирин II представляет собой крайне неустойчивое соединение, которое легко гидролизуется на воздухе молекулами атмосферной воды с образованием гидроксокомплекса. При этом динамика порфиринового кольца не претерпевает заметных изменений.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>металлопорфирины</kwd><kwd>термическая устойчивость</kwd><kwd>ИК-</kwd><kwd>ЯМР-</kwd><kwd>электронная спектроскопия</kwd><kwd>масс-спектрометрия</kwd></kwd-group><kwd-group xml:lang="en"><kwd>bismuth</kwd><kwd>metalloporphyrins</kwd><kwd>thermal stability</kwd><kwd>FT-IR</kwd><kwd>NMR</kwd><kwd>UV-VIS spectroscopy</kwd><kwd>mass spectrometry</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">висмут</mixed-citation><mixed-citation xml:lang="en">Yang Y., Ouyang R., Xu L., Guo N., Li W., Feng K., Ouyang L., Yang Z., Zhou S., Miao Y.
