【摘要】 测定了ＶＯＳＯ＿４－谷氨酸（Ｇｌｕ）－邻菲啉（ｐｈｅｎ）及ＶＯＳＯ＿４－谷氨酸－联吡啶（ｂｉｐｙ）三元混配配合物在不同酸度下（ｐＨ＝１～１４）的乙二醇／水（１：１）溶液中的低温（１７３Ｋ）ＥＳＲ谱．发现随ｐＨ的变化形成各种结构和组成的配合物，利用Ｊｏｈｎｓｏｎ的加合规则、结合配合物的ＩＲ光谱推测了各种配合物的可能结构；利用电子光谱数据计算了配合物的晶体场多数；讨论了谷氨酸、π受体配合物的成配规律。更多还原

【Abstract】 ESR spectra of VO²⁺－Glu-phen and VO²⁺－Glu-bipy ternary systems in glycol-water（1：1） solution at various acidity have been observed at low temperature（173K）．It has been found that in different pH ranges the complexes with different structures were formed. According to Johnsons rule and IR data,their possible struc-tures are suggested．Using electronic spectral data，the crystal field parameters were calculated.更多还原
