以8-氨基喹啉,高氯酸锌和叠氮酸钠为原料,通过溶剂热反应合成了一种新型的单核配合物[Zn(8-aminoql)2(N3)]·Cl O4(1),其结构经FT-IR,元素分析和X-射线单晶衍射表征。1(CCDC:1 028 430)属单斜晶系,P2/c空间群,晶胞参数a=8.445 2(7),b=6.878 1(6),c=16.437 3(13),β=93.72(3)°,V=952.78(14)3,Z=2,Dc=1.726 g·cm-3,μ=1.474 mm-1,F(000)=504,R1=0.052 4,wR2=0.140 4[I〉2σ(I)]。中心Zn(II)为五配位构型,分别与五个N原子配位,其中4个N原子来自两个8-氨基喹啉配体,一个N原子来自N3-。1通过分子间弱的氢键(N-H┈O)和芳环间π…π堆积作用构成三维超分子结构。固体荧光性能测定结果表明:在355.0 nm波长激发下,1的最大发射波长位于516.4 nm。
A new complex, [ Zn (8-aminoql) 2 ( N3 ) ] · C104 ( 1 ), was synthesized by solvothermal reaction, using 8-aminoquinoline, Zn ( C104 ) 2 and NaN3 as raw material. The struxture was characterized by FT-IR, elemental analysis and single crystal X-ray diffraction. 1( CCDC: 1 028 430) belongs to monoclinic, space group P2/c with a = 8. 445 2 (7) A, b = 6. 878 1 (6) A, c = 16.437 3 (13) A,,β =93.72(3)°, V =952.78(14)A3 , Z = 2, Dc = 1. 726 g · cm-3 , μ = 1. 474 mm-1 , F(000) = 504, R1 = 0.052 4, wR2 = 0. 140 4 [ I 〉 2σ-(I) ]. In 1, the Zn (II) has a distorted square pyramidal coordination geometry, and was coordinated by four nitrogen atoms from two 8-aminoql ligands, one nitrogen atom from one N3-. 1 presents a three-dimensional supramolecular structure via the N - H……O hydrogen bonds and π……π stacking interactions. The fluorescence property of 1 was investigated by FL. The results showed that λcm of 1 was 516.4 nm under 355.0 nm excitation.
