Dibrom(dimethylamino)alan und Diiod(dimethylamino)alan. Darstellung und Kristallstruktur / Dibromo(dimethylamino)alane and Diiodo(dimethylamino)alane. Preparation and Crystal Structure
View through CrossRef
Abstract
The title compounds were prepared by reaction of dimethylaminoalane with mercury - (II) dibromide and diiodide, respectively, and investigated by X-ray diffraction. Both compounds build structures isotype with that of dichloro(dimethylamino)alane. The molecules exist as dimers with a planar four-membered ring of alternating aluminium and nitrogen atoms. These atoms are four-coordinated. The following bond lengths are found: Al-N 1.94 and 1.95 Å, Al-Br 2.26 Å, Al-I 2.49 Å, N-C 1.50 and 1.55 Å.
