It is shown that the molecules of R1N=Y (Y=CR2R3, NR2, O) are promising for searching agents for copper clusters, as they are synthetically-available, can exert reducing properties, are firmly bound to the copper atoms, and do not distort the original cluster structure. Using any bulky substituent R, it is possible to block access to a large surface area of the cluster for aggressive compounds. Oxygen complexes on the surface of the copper cluster drastically fall short of the strength of the structures formed by molecules R1N=Y (Y=CR2R3, NR2, O). Depending on the cluster size, the interaction force varies in a sinusoidal manner from minimum to maximum.</p></abstract><trans-abstract xml:lang="ru"><p>При помощи расчетов методом теории функционала плотности систематически исследован процесс образования комплексов азотсодержащих молекул с малыми кластерами меди Cun(n=1-7, 13). Показано, что молекулы R1N=Y (Y=CR2R3, NR2, O) перспективны для поиска присадок для кластеров меди, так как являются синтетически доступными, имеют возможность проявлять восстановительные свойства, прочно связываются с атомами меди и не искажают исходную структуру кластера. Используя любой объемный заместитель R, можно блокировать доступ к большой площади поверхности кластера для агрессивных соединений. Комплексы кислорода на поверхности медного кластера существенно уступают в прочности структурам, образованным молекулами R1N=Y (Y=CR2R3, NR2, O). В зависимости от размера кластера сила взаимодействия изменяется синусоидально от минимума к максимуму.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>поверхность</kwd><kwd>нанокластер</kwd><kwd>медь</kwd><kwd>гибридизация азота</kwd><kwd>механизм роста</kwd><kwd>теория функционала плотности</kwd><kwd>комплексообразование</kwd><kwd>surface</kwd><kwd>nanocluster</kwd><kwd>copper</kwd><kwd>hybridization of nitrogen</kwd><kwd>growth mechanism</kwd><kwd>density functional theory</kwd><kwd>complex formation</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">Jug, K.
