Abstract: | Reaction of AlMe3 with NH2(C5H9) caused the evolution of methane and produced the dimeric species bis(μ‐cyclopentylamino‐N:N)bisdimethylaluminium(III)], Al(CH3)2‐(C5H10N)]2, which was found to adopt a cis configuration of cyclopentyl groups about a bent AlNAlN ring (which has twofold crystallographic symmetry) instead of the more common trans arrangement. |
