Treatment of 1,1,4,4-tetramethyl-2,3-diazabutadiene with the alane adduct [AlH 3 (NMe 2 Et)] yielded the hydrazine derivative (AlH 2 ) 2 -(AlH) 2 (N 2 iPr 2 ) 3 (1) by the hydroalumination of both C À N double bonds. Compound 1 has a complicated cage structure formed by three hydrazido groups and fo
