摘要: 测定了VOSO4-谷氨酸(Glu)-邻菲啉(phen)及VOSO4-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。

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 structures are suggested.Using electronic spectral data,the crystal field parameters were calculated.
