英文摘要	Three new oxidovanadium complexes as potential functional model vanadium-dependent haloperoxidases. [VO2(C9H7NO3)](C10H10N2)(0.5) (1). [VO(C10H8N2)(C9H7NO3)](3) (2) and [VO(C12H8N2)(C9H7NO3)] 2.33H(2)O (3) have been designed and synthesized under room temperature with mixed solution of CH3OH and H2O. All the complexes have been characterized by elemental analysis, IR spectra, UV-vis spectroscopy and X-ray single crystal diffraction The structural analysis indicates that the three complexes are all containing a tridentate amino-Schiff-base (salicylideneglycinate) with imine nitrogen, phenoxyl, and carboxyl oxygen as three donor atoms. The asymmetric unit of complex 1 is formed by one [VO7(C9H7NO3)](-) anion and half of (C10H10N2)(2+) cation, in which the nitrogen atoms of 4,4'-bipy were protonated. For complex 1, the coordination environment of the central vanadium atom is almost ideal Square pyramid, while for complexes 2 and 3, the vanadium atom is a six-coordinated and in a distorted octahedral environment. It is found that there are a variety of inter- and intra-molecular hydrogen bonds in all the three complexes, What is intriguing to us is that the oxidation state of the central metal atom in complex 1 is different from that complex 2 and 3 the oxidation state of vanadium in complex 1 is +5. while ones in complex 2 and 3 are +4 Bromination reaction activity of the complexes has been evaluated by the method with phenol red as organic substrate in the presence of H2O2, Br- and phosphate buffer, indicating that they can be considered as potential functional model vanadium-dependent haloperoxidases In addition, thermal analysis, voltammetry and quantum chemistry Calculations were also performed and discussed in detail.
