英文摘要：

A novel compound [Cu（C5H5FeC5H4SO2C9H8N2）2Cl2] was synthesized by the reaction of a novel ligand 1,4-bis（1-ferrocenesulfonyl-2-benzimidazolyl） butane with CuCl2.Its structure was character-ized by X-ray diffraction analysis,which belongs to monoclinic system with space group C2/c and cell pa-rameters of a=2.2221（2） nm,b=1.7621（2） nm,c=0.9596（8） nm,β=101.81（3）°,V=3.678（5） nm3,Dc=1.663 g/cm3,μ=1.658 mm-1,F（000）=1876,Z=4,R1=0.0935,wR2=0.1802.Copper（II） was coordinated to the ligand to form distorted tetrahedral configuration.Crystal packing of the title compound along c-axis was presented for a number of linked traditional chinese lucky pattern ＂囍＂ character structure.The theo-retical investigation of the title compound as a structure unit was fully optimized by B3LYP/6-31＋g（d） method in Gaussian 03 package,and the distribution of atomic charges and the energy and composition of frontier molecular orbits were also analyzed,which provided a good testimony for the coordination condi-tion in the crystal structure.The antimicrobial activities of the title compound against Escherichia coli and Staphyloccocus aureus were determined by spread plate method.The preliminary results showed that it had nice inhibition effect on the growth of Escherichia coli and Staphyloccocus aureus.
