Cubane‐Like Li 4 H 4 and Li 3 H 3 Li(OH): Stabilized in Molecular Adducts with Alanes

One in seven : A Li 4 H 4 unit that is coordinated with three bis(amino)alane units takes the form of a cube; the compound was isolated in molecular form and characterized by X‐ray analysis (see molecular structure; pink Li, blue N, gray Al, white H, yellow Si). During the reaction of this molecule with an equimolar amount of water only one of the seven H atoms reacts to give the hydrolysis product Li 4 H 3 (OH)[HAl{N(SiMe 3 )} 2 ] 3 .
