A core with corners : The first alumoxane containing an {Al 4 O 2 } core as well as a gallium congener with an {Al 2 Ga 2 O 2 } core are prepared by the reaction of an organoaluminum monohydroxide with MH 3 ⋅NMe 3 (see formula; M=Al, Ga; Ar=2,6‐ i Pr 2 C 6 H 3 ). These compounds contain reactive hydride groups on the central M 2 O 2 rings and methyl groups on the terminal aluminum atoms.
