摘　　要：合成了未见文献报道的双呋喃甲醛缩乙二胺与Zn2 + 的Schiff碱配合物 ,通过单晶X射线衍射法测定了其结构 .晶体属于单斜晶系 ,空间群P2 ( 1) /n ,a =0 8780 ( 11)nm ,b =1 44 61( 18)nm ,c =1 14 95 ( 15 )nm ,α =90° ,β =94 12 1( 18)° ,γ =90° ,V =1 45 6( 3 )nm3 ,Z =4,F( 0 0 0 ) =712 ,μ =2 0 5 1mm-1,R1=0 0 471,wR2 =0 0 85 7.用Gaussian 98程序计算了该配合物的键长、键角、电荷布局和频率 .通过荧光光谱研究了配体与配合物的荧光性质 ,并通过元素分析、红外光谱。The novel ligand of N,N′-bis(furfurylidene)ethylenediamine and a novel complex [ZnCl 2(C 12H 12N 2O 2)] have been synthesized and characterized by elemental analysis, UV, IR spectroscopy, fluorescence spectra and thermal analyses. The crystal structure of complex was determined by X-ray diffraction analysis. The crystal is monoclinic with space group P2(1)/n and crystal parameters of a=0 8780(11) nm, b=1 4461(18) nm, c=1 1495(15) nm, α=90°, β=94 121(18)°, γ=90°, V=1 456(3) nm 3, Z=4, F(000)=712, μ=2 051 mm -1, R 1=0 0471 and wR 2=0 0857. Quantum chemical computation was performed on the complex using Gaussian 98 program. The bond lengths, bond angles, frequency and atom charge of the complex were obtained. The fluorescence of ligand and complex was also studied.
