本文考察了VOSO_4与α,α′-联吡啶,3,4,7,8-四甲基-1,10-邻菲罗啉和1,10-邻菲啰啉在不同酸度(pH=1—14)的乙二醇-水(1:1)溶液中,低温下的ESR波谱.发现当pH<1.0时A=118×10~(-4)T,归属于[VO(H_2O)_5]~(2+);当pH>11时A=90×10~(-4)T,归属于[VO(OCH_2CH_2O)_2]~(2-).1.0 11, A = 90 × 10 -4 T, belonging to VO (OCH_2CH_2O) _2] ~ The ligands generated four or three different complexes, respectively, and the possible structures of these ligands were speculated. Using the measured spectral parameters, the bond parameters and electron energy levels were calculated. It was found that the value of the bond parameter increased with increasing pH Decrease, and the electron level data agree well with the experimental results.The crystal field parameters of VO (phen) _2 ~ (2+) have also been calculated using the electron spectroscopy data.
