The first example of a well‐defined binary, low‐oxidation‐state aluminum hydride species that is stable at ambient temperature, namely the dianion in [{( Dep Nacnac)Mg} 2 (μ‐H)] 2 [H 3 Al‐AlH 3 ] ( Dep Nacnac=[(DepNCMe) 2 CH] − , Dep=2,6‐diethylphenyl), has been prepared via a magnesium(I) reduction of the alanate complex, ( Dep Nacnac)Mg(μ‐H) 3 AlH(NEt 3 ). An X‐ray crystallographic analysis has shown the compound to be a contact ion complex, which computational studies have revealed to be the source of the stability of the aluminum(II) dianion.
