Grignard compounds and amines were converted into “dimagnesylamines” RN‐(MgX) 2 as long ago as 1903. Now for the first time a crystalline compound has been obtained from a PhN(MgBr) 2 solution in ether and characterized by X‐ray structure analysis. The title compound has a Mg 6 N 4 adamantanyl framework; each Mg 2+ ion is solvated by an ether molecule, and the four Br − ions are located above the four hexagonal faces of the Mg 6 N 4 cage.
