solvate crystal has been isolated from slow solvent evaporation method and the structure was characterized by FT-IR, NMR and Single crystal XRD. The compound crystallizes in the triclinic space group P \(\overline1 }\) with a = 7.7925(16), b = 10.716(3), c = 13.952(3), α = 106.545(5), β = 97.514(5), γ = 110.152(5), V = 1014.0(4) Å3 and Z = 1. The single crystal X-ray data of the compound confirms
采用慢速溶剂蒸发法分离得到双-[2-(3,4-二羟基苯基)-4,5-二苯基-1H-咪唑-3-鎓]草酸乙醇溶剂化物晶体,并通过FT-IR、NMR对其结构进行了表征和单晶 XRD。该化合物在三斜空间群 P \(\overline1 }\)中结晶,其中 a = 7.7925(16), b = 10.716(3), c = 13.952(3), α = 106.545(5), β = 97.514 (5),γ = 110.152(5),V = 1014.0(4) Å3,Z = 1。该化合物的单晶 X 射线数据证实了从草酸到两个嘧啶型氮的两个质子转移分离咪唑环。草酸咪唑鎓的结构和对称性由 N-H⋯O 和 O-H⋯O 氢键相互作用决定,并通过氢键分析和赫什菲尔德表面分析得到证实。咪唑鎓环中的部分双键特征证实了整个分子框架的离域。 C-O 键的部分双键特征也证实了草酸根阴离子的离域。该晶体为三维结构,
