8-氨基喹啉席夫碱锌配合物的合成,晶体结构及发光性质
Synthesis,Crystal Structure and Luminescence Property of a Zinc Complex Containing 8-aminoquinoline Schiff Base Ligand
【摘要】 合成了一个新的锌配合物[Zn(8-ahsb)(N3)](1)(8-ahsb=8-氨基喹啉水杨醛席夫碱阴离子),并对其进行了元素分析、红外光谱和X-射线单晶衍射表征。配合物1属于单斜晶系,空间群为C2/c,a=0.6762(3)nm,b=2.2842(9)nm,c=1.8162(8)nm,β=91.309(7)°,V=2.805(2)nm3,Z=8。中心离子Zn(Ⅱ)为三角双锥配位构型,分别与四个N原子、一个氧原子配位,其中1个8-氨基喹啉席夫碱配体提供了2个N原子、一个氧原子,剩余两个N原子分别来自于两个N3-阴离子,且每个N3-桥联邻近的两个Zn2+形成一维无限链状结构。荧光光谱的分析表明该化合物具有强的绿色发光性能,且可作为荧光探针检测低浓度的铜离子。
【Abstract】 A new one-dimensional chain-like complex,[Zn( 8-ahsb)( N3) ]( 1)( 8-ahsb = N-( 8-aminolyl) salicyladimine) was synthesized and characterized by elemental analysis,FT-IR and single crystal X-ray diffraction. Complex 1 crystallizes in the monoclinic system with C2/c space group,a = 0.6762( 3) nm,b = 2. 2842( 10) nm,c = 1. 8162( 8) nm,β = 91. 309( 7) °,V = 2. 805( 2) nm3,Z = 8.In complex 1,the Zn2+has a distorted trigonal-bipyramidal coordination geometry coordinated by two nitrogen atoms and one oxygen atom from one 8-ahsb ligand,two nitrogen atoms from two different N3- anions. The adjacent Zn2+were bridged via the N3-anion to form a one-dimensional infinite chain.Meanwhile,complex 1 presents strong green fluorescence in the solid state and is a potential material of fluorescence probe to detect low concentration Cu2+.
