architectures of these molecules were stabilized by classical hydrogen bonds and C–H⋯O interactions. Furthermore, the U-shaped conformation observed in the solid state of all the compounds has been analyzed using DFT calculations, AIM analysis and the NCI plot index. It reveals the existence of two intramolecular interactions, which are NH⋯π and unconventional π–π interactions involving the hydrazido
本研究描述了五种新的并入直链和支链烷基链的肼基磺酰胺衍生物的合成。一种有效而直接的合成方法被用来以高收率获得这些磺酰胺化合物。通过光谱方法和单晶X射线衍射分析对合成的化合物进行了充分表征。U形肼基磺酰胺类化合物的结构分析表明,它们的晶体堆积存在显着相似之处。这些分子的超分子结构通过经典的氢键和C–H⋯O相互作用得以稳定。此外,已使用DFT计算,AIM分析和NCI绘图指数分析了所有化合物在固态下观察到的U形构象。它揭示了两个分子内相互作用的存在,
