Adducts of AlH3 formed by direct hydrogenation showing (a) dimethylethylamine (DMEA) alane, (b) triethylenediamine (TEDA) alane, (c) trimethylamine (TMA) alane, (d) quinuclidine alane, and (e) hexamine alane. It is important to note that amine alane adducts can form different complexes (e.g., mono, bis, and dimer) depending upon conditions (e.g., concentration). The structures shown are not necessarily the most stable configurations.
