functional theory (DFT/B3LYP) quantum chemical method with the 6–311++G(d,p) basis set using the crystallographic coordinates. Additionally, fragments contributing to the HOMO and LUMO molecular orbitals were investigated at the same level of theory. The nature and various types of intermolecular interactions in the crystal structures was also investigated by Hirshfeld surface analysis. The synthesized
本研究报告研究各种非共价相互作用的中的超分子组装体的意义(ë)-1-(1-(4-硝基苯基)亚乙基)-2-苯基肼1C和(Ë)-3-溴Ñ “ - (1-苯基亚乙基)苯甲酰肼2d。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。超分子组装体的拓扑结构受到各种非共价相互作用的控制,包括经典的氢键键合,C H…π和Br…Br相互作用,这些相互作用已使用几种理论方法和DFT计算进行了详细研究。化合物1c和2d的最佳几何参数使用密度泛函理论(DFT / B3LYP)量子化学方法,使用晶体学坐标,在6–311 ++ G(d,p)基础上进行计算。此外,在相同的理论水平上研究了有助于HOMO和LUMO分子轨道的碎片。还通过Hirshfeld表面分析研究了晶体结构中分子间相互作用的性质和类型。还研究了合成的席夫碱的药物潜力和理化性质。针对四种癌细胞系(NCI-H460,NCI-H460 / Bcl
