摘要: Abstract Reaction of adamantylmagnesium bromide, AdaMgBr (Ada=C 10 H 15 ) with aluminum(III) chloride, gallium(III) dimethylgallium or dimethylaluminum chloride gives [Mg 3 BrCl (OEt)(OEt 2 6 ][Ada AlBr] ( I ), Br Cl (OEt GaBr ] II 4 GaMe III and AlMe IV respectively. These ionic compounds, characterized by 1 H- 13 C-NMR, elemental analyses, single crystal X-ray diffraction, contain trimetallic magnesium cations each alkaline earth metal residing in a distorted octahedral environment. The aluminum gallium atoms the adamantyl-based anions reside tetrahedral environments. substances are first examples Group organometallic compounds.
