   <abstract xml:lang="ru">
    <p>Методом рентгеноструктурного анализа установлена структура 2-(дихлорометил)-4-фенил-3Н-1,5-бензодиазепина (I) и двух его производных, различающихся типом заместителя в бензофрагменте: 2-(дихлорометил)-7,8-дифтор-4-фенил-3Н-1,5-бензодиазепина (II) и 2-(дихлорометил)-7-метил-4-фенил-3Н-1,5-бензодиазепина (III). В кристаллах соединений за счет реализации С-Н…N взаимодействий наблюдается образование центросимметричных Н-димеров молекул. Однако за счет π-электронных контактов Н-димеры образуют стопки, которые ориентированы вдоль наименьшего параметра элементарной ячейки, в то время как несимметричное замещение атомов водорода в бензофрагменте на метильную группу стерически препятствует образованию стопок Н-димеров, приводя к двумерной - слоевой супрамолекулярной структуре. Показаны корреляции между параметрами элементарной ячейки и ориентацией супрамолекулярных структур в кристаллах бензодиазепинов. </p>

    <p>The single-crystal X-ray diffraction method for investigation of the structure of 2-dichloromethyl-4-phenyl-3H-1,5-benzodiazepine (I) and two derivatives, namely, 2-dichloromethyl-7,8-difluoro-4-phenyl-3H-1,5-benzodiazepine (II) and 2-dichloromethyl-7-methyl-4-phenyl-3H-1,5-benzodiazepine (III) have been used. The basic supramolecular fragment in the crystals of these compounds is centrosymmetric H-dimer of the molecules formed by the C-H...N-type hydrogen bonds. Due to the C-H…π short contacts these dimers form stacks oriented along the smallest unit cell parameter, whereas asymmetrical substitution of hydrogen atoms by the methyl group at the benzofragmente sterically prevents the formation of stacks of H-dimer, resulting in a two-dimensional - layered supramolecular structure. The correlations between the unit cell parameters and orientation of supramolecular structures in the crystals of benzodiazepine have been shown. </p>
