(AIM) and NCIplot. The computation of the energy features of the diverse noncovalent interactions including C H⋯π, π⋯π and lp⋯π-hole interactions revealed their conspicuous role in the stabilization of the three-dimensional supramolecular frameworks for both compounds in addition to the C H⋯O/S H-bonding interactions.
摘要 通过 3-(4-aryl)-2-thioxo-1 的 Knoevenagel 缩合反应合成了两种新的 3-aryl-5-(4-nitrobenzylidene)-2-thioxothiazolidin-4-one 衍生物 (1 & 2), 3-thiazolidin-4-ones 与 4-硝基苯甲醛。两种产物均以良好的收率分离为橙色结晶固体,并通过分析、光谱和结构方法进行了充分表征。通过密度泛函理论 (DFT) 计算 (M06-2X/def2-TZVP)、分子静电势 (MEP) 表面分析在固态中观察到的标题化合物的有趣超分子组装,并通过巴德的“分子中的原子”(AIM)和 NCIplot。包括CH⋯π在内的多种非共价相互作用的能量特征的计算,
