Reaction of the n ‐propyl‐bridged bis(aminotroponimine) H 2 [( i Pr)TP] with various dialkylaluminum hydrides R 2 AlH, in hexane, led to novel bimetallic compounds of composition [(R 2 Al) 2 {( i Pr)TP}] (R = Me, Et, i Bu). Depending on the size of the substituents R bound to the Al centers the complexes crystallize either in a cisoid (R = Me) or a transoid (R = i Bu) conformation. The steric crowding at the aluminum centers is also observed in solution.
