苯三甲酸和盐酸胍为主体晶格管状包合物的晶体结构

合成了苯三甲酸和盐酸胍共同构建主体晶格的正四丁基铵阳离子管状包合物(C4H9)4N+·2C(NH2)+3·1,3,5-C6H3(COO-)3·3H2O,并通过单晶X射线衍射法对其进行了晶体结构测定。结果表明:包合物中苯三甲酸阴离子和盐酸胍阳离子氢键连接形成的宽链借助水分子氢键连接在一起,形成沿bc平面无限延伸的二维氢键褶皱层,构成类长方形管道的一对管壁,另一盐酸胍阳离子穿插在氢键层中,构成管道的另一对管壁,每个管道内包含两列规则排列的正四丁基铵阳离子(n-C4H9)4N+。

Novel inclusion compound built of tunnel-type host lattices constructed by guanidine hydrochloride and 1,3,5-benzenetricarboxylic acid

A new inclusion compound, （C4H9）4N＋· 3H20, has been prepared and characterized by X - ray c 2C（NH2）3＋＋ 1,3,5 - C6H3 （COO-）3· rystallography. Results show that：In the crys- tal structure of the title compound, a pair of opposite walls of the rectangle channel - like lattice is built of a parallel arrangement of puckered hydrogen bonds layers that are interlinked by benzenetricar- boxylic acid anion and guanidine hydrochloride cation and formed along the BC limitless extension of planar two - dimensional hydrogen bond fold layer. A class rectangle pipe of a pair of tube wall. Anoth- er pair of walls is formed by guanidine hydrochloride cation. Each pipe contains two columns of regu- larly arranged is tetrabutyl ammonium cations（ n- C4H9 ）4N＋
