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.
