В ряде случаев проводились квантово-химические расчеты. Кроме 1Н и 13С, использовались также спектры ЯМР от других ядер. Изучалось пространственное и электронное строение молекул различных классов, содержащих в своем составе гетероатомы (азот, кислород, серу, кремний, фосфор), а также различные функциональные группы. Серия работ относится к изучению координационных соединений (диамагнитных и парамагнитных), а также комплексных соединений донорно-акцепторного типа. Установлены области значений параметров спектров ЯМР (химических сдвигов и констант спин-спинового взаимодействия, включая величины дальних констант спин-спинового взаимодействия, характерные для азольного цикла) и наиболее известных функциональных групп, входящих в состав замещенных имидазолов и пиразолов. Показано, что указанные параметры могут быть использованы для установления пространственного и электронного строения вновь синтезируемых соединений, содержащих азольный гетероцикл. Проведен анализ спектров ЯМР 1Н и 13С растворов комплексов 1-винилимидазола с хлоридами марганца, кобальта, никеля и меди, а также с органилгалогенстаннанами (C2H5)3 SnX. Доказано, что в растворе парамагнитных комплексов 1-винилимидазола с хлоридами элементов первой переходной группы координирующий атом имеет октаэдрическое окружение, причем четыре молекулы лиганда занимают экваториальное положение. Структура диамагнитных комплексов этого азола с органилгалогенстаннанами представляет собой тригональную бипирамиду. Отработан метод изучения молекулярного строения, основанный на использовании явления ЯМР в парамагнитных системах. Рассмотрены примеры (производные 1-замещенных азолов) применения спектров ЯМР, измененных сверхтонким взаимодействием, для решения различного рода задач, связанных со строением и внутримолекулярной динамикой многоэлектронных систем.</p></abstract><trans-abstract xml:lang="en"><p>The structure and composition of many-electron molecular systems were analysed by nuclear magnetic resonance (NMR) spectra obtained from hydrogen and carbon atom nuclei, NMR 1H and 13C. In some cases, quantum chemical calculations were carried out. In addition to 1N and 13C, NMR spectra from other nuclei were also used. The spatial and electronic structure of molecules of various classes containing heteroatoms (nitrogen, oxygen, sulphur, silicon and phosphorus), as well as various functional groups, were studied. A series of papers deal with coordination compounds (diamagnetic and paramagnetic), as well as complex compounds of a donor-acceptor type. Parameter domains of NMR spectra — chemical shifts and spin-spin interaction constants — were determined, including the values of long-range spin-spin interaction constants characteristic of the azole cycle and well-known functional groups that make up substituted imidazoles and pyrazoles. It was shown that the indicated parameters can be used to establish the spatial and electronic structure of newly synthesized compounds containing an azole heterocycle. The study involved the analysis of NMR spectra 1H and 13C of solutions of 1-vinylimidazole complexes with manganese, cobalt, nickel and copper chlorides, as well as with organylhalogenostannanes (C2H5)3 SnX. In a solution of paramagnetic complexes of 1-vinylimidazole with chlorides of elements of the first transition group, the coordinating atom proved to have an octahedral environment, with four ligand molecules occupying the equatorial position. The structure of the diamagnetic complexes of this azole with organylhalogenostannanes is a trigonal bipyramid. A method for studying molecular structures based on NMR in paramagnetic systems is proposed. Examples (derivatives of 1-substituted azoles) of using NMR spectra modified by ultrafine interaction for solving various problems related to the structure and intramolecular dynamics of many-electron systems are provided.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>спектроскопия ЯМР</kwd><kwd>1-замещенные азолы</kwd><kwd>координационные соединения</kwd></kwd-group><kwd-group xml:lang="en"><kwd>NMR spectroscopy</kwd><kwd>1-substituted azoles</kwd><kwd>coordination compounds</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">Ocansey E., Darkwa J., Makhubela B.C.E.
