Synthesis and structure of tetrakis(isopropylimino)bis-[tris(dimethylamino)silylamino]alane

Tris(dimethylamino)silylamine H2NSi(NMe2)3 reacts with poly(isopropyliminoalane) (HAlNiPr)6 leading to the formation of a novel cage-type compound tetrakis(isopropylimino)bis[tris(dimethylamino)silylamino]alane, H6Al6(NiPr)4[NSi(NMe2)3]2. The molecular structure has been determined on the basis of its FTIR, NMR and X-ray crystallographic analysis.
