Its bonding characterization and stability are discussed. The results show that these complexes are covalence complexes and that both the in-plane σ-bond and the in-plane π-bond in these complexes play an important role. The ESR spectra of VO -Ser system, VO -Ser-Phen system and VO -Ser-Bipy system in binary solvent glycol/water (V/V=1: 1) solution at various acidities (pH=1～14) have been observed at low temperature. It is found that in different pH ranges different structural complexes are formed.

According to Johnson's Rule and IR spectra, their possible structures are suggested. The bonding parameters of those complexes are calculated by ESR parameters. And the crystal field parameters are calculated by using electronic spectral data. It can be seen that the vanadyl complexes in the solution are ionic complexes and that the α〓 values of those complexes decrease following the increasing of the N donor replacing the O donor of water on the equatorial plane in those complexes. This means that the covalent bonding between vanadium and ligand increases as Ser, Phen or Bipy replace water ligands. The results show the competitive coordinate law that the coordination reactivity of Phen and Bipy is much stronger than that of Ser. The simulation program of ESR is compiled by the theory of ESR in the present work.

测定了VO-丝氨酸二元体系、VO-丝氨酸-邻菲咯啉三元体系和VO-丝氨酸联吡啶三元体系在不同酸度下（pH=1.0～14.0）的乙二醇／水（V／V=1：1）溶液低温ESR谱，发现不同pH下，溶液中具有不同组成的配合物，根据不同pH下ESR谱的变化，利用Johnson的加合规则并结合红外光谱，推测了它们在溶液中的可能结构；利用波谱参数计算了配合物键参数；利用电子光谱数据计算了配合物的晶体场参数，讨沦了它们的成配特性，结果表明：VO配合物属离子型配合物，随取代水分子的配体（Ser、Phen或Bipy）数目增加，键参数减小，配合物共价性增强，同时得出这些体系中，生物配体竞争配位规律：Phen和Bipy与VO的配位能力比Ser强。

A novel Belousov-Zhabotinskii type oscillating reaction was observed in a closed serine-BrO^-~3-Mn^2^+- H2SO4 system(Ser-BZ system), which exhibited the followign characteristics:(1)Although Ser is unable to be brominated, the sustained oscillations could still be observed in the above system under batchreactor conditions even in the absence of either acetone or inert gas flow.(2)The present oscillations displayed extremely short induction period(0) and very few oscillation number(1).(3)Cl^-, acrylonitrile, or Br^- could effectively inhibit the oscillations. However, in the case when enough Ag^+ was addedinto the system to completely inhibit the oscillations in , the oscillations on the Pt-electrode could still be observed.
