The crystal structures of the host-guest supramolecular complexes [2(6-HPCH)2+.3(18C6)].4[ClO4¯].2(H2O) (I) and [(PDA)2+.2(18C6)].2[Cl¯].10(H2O) (II) (18C6 = 18-crown-6; 6HPCH = 6-hydrazinylpyridine-1-ium-3-carbohydrazinium; PDA = p-phenylenediaminium) were determined by single-crystal X-ray diffraction analysis. Supramolecular assembly is constructed by NH···O, OH···O and C-H···O interactions. Both
主客体超分子复合物 [2(6-HPCH) 2+ .3(18C6)].4[ClO 4 ¯].2(H 2 O) (I) 和 [(PDA) 2+ ] 的晶体结构。 2(18C6)].2[Cl¯].10(H 2 O) (II) (18C6 = 18-crown-6; 6HPCH = 6-hydrazinylpyridine-1-ium-3-carbohydrazinium; PDA = p -phenylenediaminium )通过单晶 X 射线衍射分析确定。超分子组装是由N ·H···O、O ·H···O和CH···O相互作用构成的。均属于具有中心对称空间群 P2 1 / n的单斜晶系. FT-IR 中的振动模式用于识别功能组。通过漫反射光谱估算的直接带隙能量为,(I) 为 3.42 eV,(II) 为 4.78 eV。通过源自单晶 XRD 数据的 Hirshfeld 表面分析分子相互作用。Hirshfeld
