Рентгеноструктурные измерения показывают, что кластеры Fe2NiO комплексов обладают симметрией, близкой к кристаллической симметрии класса 3. Для лигандов, координированных с различными металлами, обнаружена практически эквивалентность ИК спектров, но не эквивалентность спектров ЯМР. Результаты ЯМР показывают наибольший химический сдвиг 1Н 95.1 м.д., что указывает на парамагнетизм комплекса, который ослаблен антиферромагнитным взаимодействием ионов металлов через мостик μ3-О. Согласно результатам ЯМР и ИК исследований, комплексы стабильны в различных неполярных и умеренно полярных растворителях, таких как CDCl3 и d3-MeCN, но разлагаются на ионы металлов и соответствующие лиганды в сильных полярных растворителях, таких как вода, при комнатной температуре. Сопоставление в 1Н ЯМР спектрах проводилось на основе анализа относительных интенсивностей, уширения, экспериментов при различных температурах, времен спинрешеточной релаксации и замещения соответствующими лигандами. Эксперименты по спин-решеточной релаксации 1H и измерения методом ЯМР при переменной температуре осуществлялись также для исследования структур растворов и динамики комплексов. Химический сдвиг 1Н для пиридина, скоординированного с металлами, может превышать 90 м.д.</p></abstract><trans-abstract xml:lang="en"><p>Two μ3-oxo carboxylate-bridged heteronuclear complexes, [Fe2IIINiIIO(O2CC2H5)6(H2O)3]·H2O and [Fe2IIINiIIO(O2CC2H5)6(py)3] ·py, were prepared and characterized by several spectroscopic techniques including NMR, X-ray diffraction, IR, ESR, and UV. X-ray diffraction measurements demonstrated that the Fe2NiO clusters of the complexes were close to threefold symmetry in crystals. The ligands coordinated to different metal atoms were almost equivalent in the IR timescale but in equivalent in the NMR timescale. The NMR results showed that the largest 1H NMR chemical shift of the complex was 95.1 ppm, implying its paramagnetic property, which was weakened by the antiferromagnetic interaction of metal ions through the μ3-O bridge. NMR and IR studies indicated that the complexes were stable in various nonpolar and moderately polar solvents, such as CDCl3 and d3-MeCN, but they were decomposed into metal ions and the corresponding ligands in strong polar solvents, such as water, at room temperature. Assignments of the 1H NMR spectra of the complexes were made on the basis of relative intensities, broadening, variable temperature experiments, spin-lattice relaxation times, and substitution by appropriate ligands. The 1H spin-lattice relaxation time T1 and variable-temperature NMR experiments were also applied to investigate the solution structures and dynamics of the complexes. It is worth noting that the 1H chemical shift of the pyridine coordinated to the metals could be greater than 90 ppm</p></trans-abstract><kwd-group xml:lang="ru"><kwd>ядерный магнитный резонанс</kwd><kwd>трехъядерные комплексы</kwd><kwd>оксоцентрированные комплексы</kwd><kwd>карбоксилатные комплексы</kwd></kwd-group><kwd-group xml:lang="en"><kwd>nuclear magnetic resonance</kwd><kwd>trinuclear complexes</kwd><kwd>oxo-centered complexes</kwd><kwd>carboxylate complexes</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">This work is supported by NNSF of China (81101037).</funding-statement><funding-statement xml:lang="en">This work is supported by NNSF of China (81101037).</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">M.
