摘要
采用水热合成法,得到Ag(Ⅰ)的配合物:Age(Sal)z(Sal=邻羟基苯甲酸)。对该配合物的单晶进行了X-射线衍射分析,确定了结构.配合物为单斜晶系,P2(1)/c空间群,a=0.7428(17)nm,b=0.886(2)nm,c=1.067(3)nm,β=107.92(3)°,V=0.668(3)nm^2,Z=2,Dc=2.436g/cm^3,Gof=1.301,R1=0.0860。对该配合物的UV-VIS-NIR,IR和荧光光谱进行了测定.结果表明:该配合物在λex=345nm条件下,在418~504.5nm范围内有3个发射峰,可以分别指认为LLCT和LMCT。
Transition complex. Ag2 (Sal)2 (Sal=salicylic acid) has been synthesized. The single crystal structure of the complex was determined by X-ray diffraction. It crystallizes in the Monoelinie system, space group P2(1)/c with α=0. 742 8(17) nm, b=0. 886(2) nm, c=1. 067(3) nm, β=107. 92(3)°, V=0. 668(3) nm^3, Z=2, Dc=2. 436 g/cm^3, Gof=l. 301, RI=0. 086 0. The UV-VIS-NIR ,IR and fluorescence spectra of the complex were measured. The results show that it has three emission peaks in the range of 418-504. 5 nm, with the excitation at 345nm. They can be assigned to LLCT and LMCT.
