Treatment of nitrile I with an equimolar amt. of DIBAL produces the alane complex II, which reacts sluggishly with protic nucleophiles. The x-ray crystal structure of II shows unusual geometric distortions in the Al2N2 core and about the imine C, as well as in the cyclopropene ring, all of which are attributed to the extreme steric bulk of the hydrocarbon ligands.
