Studies On Scorpionates Oxovanadium-amino-acid Complex With Potential Biological Activities

With the discovery of vanadium haloperoxidases and nitrogenase, much more interests have been concentrated on the coordination characteristic and the bioinorganic characteristic of vanadium. The physiological function and enzymes'chemical modelling for some inorganic vanadium complex, such as NaVO3,Na3VO4 and VOSO4, etc, have been studied. In this paper, using the poly(pyrazolyl)borate as supporting ligand and the ammonia acid as the second ligand, a serises of oxovanadium complexes were synthesized successfully as following: 1,VO(pz)4SO4?H2O 2,VO[PhCH2CH(NH2)COO)][HB(pz)3 3,VO(3,5-Me2pz)[HB(3,5-Me2pz)3] (CH3COO) 4,K[(B(pz)4)2 (H2O)2(H3O+)] 5,VO[B(pz)4]2The structure of complexes 1-5 are determined by X-ray crystal diffractometer, and they are mainly characterized by infrared spectrum,ultraviolet spectrum,fluorescence spectrum and thermal decomposition analysis. In addition, Using quantum calculus, the orbital'eigenvalues,net charge,natural electron configuration and bond order for all complexes are given.
