Abstract: ESR spectra of Cu(Ⅱ) complex with o-vanillin alanine in various states (polycrystalline powder or solution) and in various solvents (CH3OH, DMF and DMSO) were investigated at different temperatures. The second order effect and relaxation effect were observed on solution spectram at room temperature, that was satisfactorily explained by spin Hamiltonian. By using spectral parameters from solution spectrum at low temperature, the bonding parameters of the complex were calculated. The bonding characterization and stability of the complex were discussed.

Key words: O-vanillin alanine, Cu (Ⅱ) complex, ESR spectra
