The reaction of LAlH 2 [L = HC(CMeNAr) 2 , Ar = 2, 6‐ i Pr 2 C 6 H 3 ] ( 1 ) with 2‐[(2‐hydroxybenzylidene)amino]‐3‐mercaptopropionic acid and benzene‐1, 2‐diamine resulted in the compounds LAl[(μ‐O)( o ‐C 6 H 4 )][(μ‐O)(COCHCH 2 SH)](NCH) ( 2 ) and LAl(μ‐NH) 2 ( o ‐C 6 H 4 ) ( 3 ), respectively. Compound 2 is an unusual aluminum Schiff base, which exhibits a C 3 NAlO six‐ and a C 2 NAlO five‐membered ring, which share the same Al←N coordinate bond. Moreover the aluminum atom is five‐coordinate and functions as the center of the three heterocycles. Compound 3 features an organic‐inorganic hybrid containing a C 2 N 2 Al five‐membered ring. Complexes 2 and 3 were characterized by 1 H NMR, elemental analysis, and single‐crystal X‐ray diffraction studies.
