摘要 以吡啶类Schiff碱衍生物吡啶-3-甲醛缩4-氨基安替比林和Cd(NO3)2·4H2O为原料,采用溶剂热法合成了一个十八元环结构的配合物Cd2(NO3)4(L3)4(L3=吡啶-3-甲醛缩4-氨基安替比林),用红外光谱、拉曼光谱、X射线粉末衍射、单晶X射线衍射等手段对配合物的单晶结构进行了表征.该配合物属三斜晶系,空间群P-1,晶胞参数a=1.058 90(11)nm,b=1.222 15(12)nm,c=1.546 20(15)nm,α=74.243 0(10)°,β=78.974 0(10)°,γ=69.872 0(10)°,V=1.796 9(3)nm3,Z=2,Dc=1.514 8g/cm3,F(000)=836,μ=0.673mm-1,R1=0.033 8,ωR2=0.108 0(I>2σ(I)).室温固态荧光测试显示,配合物在513nm(λmax)具有强的荧光吸收. A novel Cadmium ( ]1 ) complex Cd2 (NO3)4 (L3)4 (L3 = pyridine-3-carboxaldehyde and 4-aminoantipy- rine) has been solvothermally synthesized and structurally characterized by elemental analysis, IR(Infrared Ray), Ra- man, XRD(X-ray diffraction), and single-crysital X-ray diffraction. The compound belongs to Triclinic system with space group P-1 and cell parameter : a=l. 0158 90(11) nm, b=l. 222 15(12) nm, c= 15. 462 0(15) nm, a= 74. 243 0(10)βl=78. 974 0(10)°,y=69. 872 0(10)°, V =1. 796 9(3) nm3, Z=2, Dc=l. 514 8 g/cm3,F(000) = 836,μ=0. 673 mm-1 , R1 = 0. 033 8,ωR2 =0. 108 0(I〉2a(I)). The Cadmium ( Ⅱ ) complex exhibits strong fluores- cence absorption at 513 nm(λm,x) in the solid sl:ate at room temperature.
