Abstract

The first example of a well-defined binary, low-oxidation-state aluminum hydride species that is stable at ambient temperature, namely the dianion in [{(^DepNacnac)Mg}₂(μ-H)]₂[H₃Al-AlH₃] (^DepNacnac=[(DepNCMe)₂CH]⁻, Dep=2,6-diethylphenyl), has been prepared via a magnesium(I) reduction of the alanate complex, (^DepNacnac)Mg(μ-H)₃AlH(NEt₃). 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.
