摘要: 研究了桥联双(甲巯咪唑)化合物(Ⅰa—Ⅳa、Ⅰb)的合成和配位性能。UV谱显示Ⅰa—Ⅳa与UO22+离子(硬酸)配位,溶液中形成3:1的配合物。Ⅰb与Hg2+、Au3+离子(软酸)配位形成2:1的配合物,用CNDO/2方法计算了各配体分子中原子净电荷密度和HOMO、LUMO能量。

Abstract: The syntheses and coordination properties of bridged bis(methimazole) compounds of Ia- IVa and Ib are studied.The UV spectra reveal that Ia- IVa coordinate UO2 (Ⅱ) (hard acid) ion into complexes with the ratio L:UO2(Ⅱ) = 3:1 and that Ib coordinates Hg(Ⅱ), Au (Ⅲ) (soft acid) ions into complexes with the ratio L:M = 2:1.The atomic net charge densities and frontier orbital (HOMO, LUMO) energies of Ia- IVa and Ib molecules were calculated by CNDO/2 method.
