中文摘要: |
以甲基碘化镁和氯金酸钾为原料,在乙醚和正己烷混合溶液中合成一种制备有机金化合物的关键中间体—二甲基碘化金([(CH3)2AuI]2)。通过元素分析、质谱、红外光谱、核磁共振氢谱和单晶X射线衍射测定和表征了其化学结构。二甲基碘化金为碘桥双核配合物,每个金原子与2个甲基和2个碘离子配位,形成四配位的平面正方形,2个配位单元通过碘离子桥联,处于同一平面。 |
英文摘要: |
Dimethylgold iodide, a key intermediates for organometallic compounds of gold, was prepared via the reaction of methyl-magnesium iodide and potassium tetrachloroaurate(III) in a mixture of ether and hexane. Its chemical structure was characterized by using elemental analysis, MS, IR, 1H-NMR along with single X-ray diffraction. The results reveal that dimethylgold iodide is a iodide-bridged dimeric compound in which each gold atom is coordinated by two methyl groups and two iodide ions, forming a planner complex unit. Two complex units are bridged together by two iodides and share the same plane. |
