中文摘要：

基于钒卤代过氧化物酶（V-HPOs）活性中心的N、O配位环境及活性中心与氨基酸残基、水分子之间的氢键作用的模拟,我们设计、合成了两种钒氧配合物：（C3H5N2）2[（VO）2（μ2-C2O4）（C2O4）2（H2O）2]（1）和（VO2）2（μ2-C2O4）（C3H4N2）2（2）,并通过X射线单晶衍射方法确定了它们的结构.晶体结构分析表明上述钒氧配合物的配位环境与（V-HPOs）活性中心十分相似,且在配合物的三维堆积结构中具有类α-螺旋结构.溴化反应活性研究发现这些钒氧配合物在仿生催化实验中表现出较高的催化活性.

英文摘要：

Based on mimicing the N,O coordination environment of the active center of vanadium haloperoxidase （V-HPOs） and the hydrogen-bond interaction between the active center and amino acid residues or water molecules,we designed and synthesized two kinds of oxidovanadium complexes：（C3H5N2）2[（VO）2（μ2-C2O4）（C2O4）2（H2O）2] （1） and （VO2）2（μ2-C2O4）（C3H4N2）2 （2）.We determined their structures by X-ray single crystal diffraction.The crystal structure analysis indicated that the coordination environments of those oxidovanadium complexes were similar to the active center of vanadium haloperoxidase,and there seemed to be a mimicing α-helix structure in the three-dimensional packing structure of the complexes.Additionally,by studying the bromination reaction activity we found that the oxidovanadium complexes had an upper activity during the mimic catalytic process.
