摘　　要：利用水热合成法,以4,5-二氰基咪唑(HIMDN)、草酸、叠氮钠和硝酸镧在原位反应下配位组装得到了一个新颖的金属-有机配合物[La2(DTIM)2(C2O4)2(H2O)4]n,并通过元素分析、红外分析、热重分析、荧光光谱和X线单晶衍射对其进行了表征.结果分析表明:配合物属于三斜晶系,P-1空间群,a=5.933 0(12),b=7.759 8(16),c=15.005(3),V=674.6(2)3,Z=1,Dcalc=2.285 mg/mm3,R1[I>2σ(I)]=0.052 6,wR2(alldata)=0.155 6.该配合物通过草酸的桥联作用表现为二维面状结构,并且通过氢键作用显示出三维结构.A novel complex [La2（DTIM）2（C2O4）2（H2O）4]n has been constructed based on the 1H-Imidazole-4,5-dicarbonitrile（HIMDN）,oxalic acid,sodium azide and lanthanum nitrate through the hydrothermal reaction of in situ,and characterized with elemental analysis,IR spectrum,thermogravimetric analysis,fluorescence spectrum and single-crystal X-ray diffraction.The experiment showed that crystal data of complex was triclinic,P-1,a=5.933 0（12）,b=7.759 8（16）,c=15.005（3）,V=674.6（2）3,Z=1,Dcalc=2.285 mg/mm3,R1[I2σ（I）]=0.052 6,wR2（all data） = 0.155 6.The 2D planar structure of the complex 1 was constructed through the bridging interaction of oxalic acid.The 3D supramolecular structure of the 1 was constructed by hydrogen bonding.
