研究了桥联双(甲巯咪唑)化合物(Ⅰ_a—Ⅳ_a、Ⅰ_b)的合成和配位性能。UV谱显示Ⅰ_a—Ⅳ_a与UO_2~(2+)离子(硬酸)配位,溶液中形成3:1的配合物。Ⅰ_b与Hg~(2+)、Au~(3+)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。
The synthesis and coordination properties of bridged bis (methimazole) compounds (Ⅰ_a-Ⅳ_a, Ⅰ_b) were studied. UV spectroscopy showed that Ⅰ_a-Ⅳ_a coordinated with UO_2 2+ ions (hard acid) to form a 3: 1 complex in solution. Ⅰ_b complexes with Hg 2+ and Au 3+ ions to form a 2: 1 complex, and the net atomic charge density and HOMO, LUMO energy.
