摘　　要：合成了一个铜单核配合物Cu(HL1)2(H2L1=2-羟基-3-(羟基亚氨基)甲基苯甲酸甲酯),利用红外光谱和X射线单晶衍射对这个配合物的结构和性质进行了表征.结果表明:该配合物属单斜晶系,C2/c空间群,晶胞参数为:a=16.939(2)nm,b=4.633(5)nm,c=23.245(3)nm,α=γ=90°,β=105.428(1)°,V=1758.3(3)nm3,Z=4,Dc=1.707 g·cm-3,μ=1.296 mm-1,F(000)=924,R1=0.0354,wR2=0.0802.配合物的结构是一个铜原子处于两个配体中间的平行四边形结构.在铜原子参与的情况下,合成的有机配体与甲醇发生了酯化反应,生成了新的配体H2L1.A copper mononuclear complex Cu(HL1)2 was synthesized, where H2L1 is 2-hydroxy-3-((hydroxyimino)methyl)benzoic acid methyl ester. The structure and properties of the complex were characterized by means of infrared spectrometry and X-ray single crystal diffraction. Results indicated that this compound belongs to monoclinic system, space group C2/c with lattice parameters a=16.939(2) nm,b=4.633(5) nm,c=23.245(3) nm,α=γ=90°,β=105.428(1) °,V=1 758.3(3) nm3,Z=4,Dc=1.707 g·cm-3,μ=1.296 mm-1,F(000)=924,R1=0.035 4,wR2=0.080 2. Structure of complex is that a copper atom is sandwiched of two molecules ligand. In the case of the copper atomundefineds participation, the synthesized organic ligand and methanol have an esterification reaction, and a new ligand H2L1 is generated.
