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 [{((Dep)Nacnac)Mg}(2)(mu-H)](2)[H3Al-AlH3] ((Dep)Nacnac=[(DepNCMe)(2)CH](-), Dep=2,6-diethylphenyl), has been prepared via a magnesium(I) reduction of the alanate complex, ((Dep)Nacnac) Mg(mu-H)(3)AlH(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.
