| Abstract: | 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. |
