摘要: 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. You can call me HAl: The first example of a well‐defined binary, low‐oxidation‐state aluminum hydride species that is stable at ambient temperature, is prepared (see picture). Computational studies reveal the stability of the aluminum(II) hydride dianion to be derived from its complexation with two bulky dimagnesium hydride cations.
