With N,N′-bis(benzimidazol-2-methyl)amine as the ligand,a novel Cu(Ⅱ) dinuclear complex was synthesized as a mimetic compound of superoxide dismutase(SOD).The complex was characterized with element analysis,UV and IR spectra.The crystal structure was determined by using X-ray diffraction analysis.the crystal structure shows that Cu(Ⅱ) and its coordinated atoms construct distorted octahedron configuration with oxygen atome of (ClO4-)s in the axial directions.The coordinated cations are linked by (ClO4-)s to form nonplanar sheets.All sheets are linked together into three-dimensional network by the intermolecular hydrogen bonds.The result of the activity assay indicates that the complex does have certain biological activity. 相似文献

Introduction Since the structures of superoxide dismutase (SOD) which appears to play an important role in both the animal and plant kingdoms to eliminate ·2O- and pro-tect living organisms from toxicity of ·2O- 1, exhibit that most of the coordinated atoms around metal ions are from imidazole groups of histidines which are the primary ligands in distorted coordination geometry2-4 in SOD, an important step should be designed to synthe-size the model compounds of SOD in which ligands shou… 相似文献
