| 摘要: 制备了铁钼硅杂多蓝阴离子[SiFeⅢMoⅤMo10ⅥO40H3]5-的钾盐和四丁铵盐,应用57Fe同位素增丰法测定了匹丁铵盐的Mossbauer谱。结合磁化率测定和红外光谱数据,研究了杂多蓝阴离子中铁的价态和自旋态等,推测由于Mo-O-Fe之间氧桥的作用,相邻金属原子上的d电子之间存在反磁性交换。实验结果肯定了这一推测。 |

| Abstract: The K+and [(C4H9)4N]+salts of heteropolymolybdate blue anion containing iron ([SiFeⅢ Mov Mo10VI040H3]5-) have been prepared. The Mossbauer spectra of the [(C4H9,)4N]+salt of the anion has been determined, using the method of 57Fe isotopic enrichment. The IR spectra and magnetic susceptibility have also been determined. The valence and spin state of iron in the anion have been studied. The experimental results show that there may be an antimagnetism exchange between d-electrons of two different metal atoms through oxygen-bridge in Mo-O-Fe. |
