摘　　要：用 4,5 二氮芴 9 酮 (dafo)、邻苯二甲酸、高氯酸铜和 4,5 二氮芴 9 酮 (dafo)、苯甲酸、高氯酸铜进行混和反应时分别得到亮蓝色和蓝绿色晶体 ,它们的结构通过单晶X射线衍射法测定 .其单晶结构表明 ,这两种化合物是同分异构体 ,组成都是C2 2 H1 6 Cl2 CuN4O1 2 .这两种化合物是通过氢键形成的具有二维网状结构的超分子化合物 ,并通过元素分析、红外光谱。The bright-blue crystals were obtained by reacting copper(Ⅱ) perchloride with 4,5-diazafluorene-9-one(dafo) and o-phthalic acid and the glaucous crystals were obtained by reacting copper(Ⅱ) perchloride with dafo and benzoic acid. Their structures were determined by single crystal X-ray diffraction. Their crystal structures indicate that the two compounds are isomeric compounds with empirical formulas C 22H 16Cl 2CuN 4O 12. The two compounds as supramolecular compounds, have two-dimensional network structures formed through hydrogen bonds. In addition, the two compounds were characterized by elemental, IR spectra and thermal analyses.
