The crystal structures of 1,2-bis(2-acetamidoethyl)diaziridine and 3,3-diethyldiaziridine have been determined by single-crystal X-ray diffraction study. The studied diaziridine molecules have C2 total group symmetry. The conformation of the studied molecules is similar to those of other diaziridines. A topological study within the framework of Bader’s atoms in molecule (AIM) theory was performed for
1,2-双(2-乙酰氨基乙基)二氮丙啶和3,3-二乙基二氮丙啶的晶体结构已通过单晶X射线衍射研究确定。研究的二氮丙啶分子具有 C2 总基团对称性。所研究分子的构象与其他二氮丙啶的构象相似。对这些分子、它们的类似物和相关化合物在巴德的分子中原子 (AIM) 理论框架内进行了拓扑研究。根据 AIM 和自然键轨道 (NBO) 分析数据,描述并量化了分子内相互作用对化学键的影响。发现 NN 键长随着 σN-N 键合轨道的 p 特征的增加而从无环分子变为环状分子。
