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.
测定了五种氨基酸席夫碱铜配合物的室温多晶粉末ESR谱、在不同溶剂中的室温及低温溶液ESR谱，确定配合物的配位环境；对室温溶液谱中观察到的二级效应和驰豫效应给予了理论解释、计算了驰豫参数；根据低温ESR波谱，计算了配合物的成键特性及稳定性，发现此类配合物为共价型配合物，平面内σ配键和平面内π配键均起重要作用。
