Reacting o ‐C 6 H 4 F(CH = NC 6 H 3 i Pr 2 ‐2,6) (L) with H 3 Al·NMe 3 resulted in the aluminum dihydride with coordinated NMe 3 of composition [ o ‐C 6 H 4 F(CH 2 NC 6 H 3 i Pr 2 ‐2,6)]AlH 2 (NMe 3 )( 1 ). Furthermore, the aluminum monohydride [ o ‐C 6 H 4 N(C 6 H 3 i Pr 2 ‐2,6)(CH 2 NC 6 H 3 i Pr 2 ‐2,6)]AlH(NMe 3 ) ( 2 ) was prepared by treatment of the anilido‐imine ligand o ‐C 6 H 4 N(C 6 H 3 i Pr 2 ‐2,6)(CH = NC 6 H 3 i Pr 2 ‐2,6) (L*) with H 3 Al·NMe 3 in high yield. The formations of the two complexes both involve aluminum hydride addition to the C=N double bond. Compounds 1 and 2 were characterized by 1 H NMR and IR spectroscopic, elementary analysis, and single‐crystal X‐ray diffraction studies.
