3,5-二氨基苯甲酸(diaba),1,10-邻菲啰啉(phen)与过渡金属镉经水热反应合成了一个新型的镉配合物[Cd(diaba)(phen)2]NO3·H2O(1),其结构和性能经IR,元素分析,X-单晶衍射,热重分析及荧光光谱表征。1属正交晶系,空间群Fddd,晶胞参数a=1.425 81(7)nm,b=2.564 62(13)nm,c=3.092 47(17)nm,Z=16,R1=0.030 2,wR2=0.079 4。1的结构单元由一个Cd(Ⅱ),一个diaba和两个phen构成,单元结构通过复杂的氢键和较强的π-π堆积形成三维超分子化合物。在335 nm波长激发下,1的最大荧光发射峰位于400 nm;1失重10.76%的温度为300℃。
Cd (diaba) (phen) 2] NO3 was synthesized by hydrothermal reaction of 3,5-diaba, 1,10-phenanthroline and transition metal cadmium · H2O (1). Its structure and properties were characterized by IR, elemental analysis, X-ray single crystal, TG and fluorescence spectra. 1 is an orthorhombic system with a space group Fddd with unit cell parameters a = 1.425 81 (7) nm, b = 2.564 62 (13) nm, c = 3.092 47 wR2 = 0.079 The structural unit of 4.1 consists of one Cd (Ⅱ), one diaba and two phens. The unit structure forms a three-dimensional supramolecular compound through complex hydrogen bonds and strong π-π stacking. Under the excitation of 335 nm, the maximum fluorescence emission peak of 1 is located at 400 nm; 1 The temperature of 10.76% weight loss is 300 ℃.
