| Abstract: | The Crystal Structure of Diethylaluminium Hypersilanide (C2H5)2Al–Si{Si(CH3)3}3]2 Et2Al–Hsi]2 (Et = C2H5, Hsi = –Si(SiMe3)3), prepared from Et2AlCl]2 and equimolar amounts of base‐free Li–Hsi in n‐pentane, crystallizes in the triclinic space group P 1 with two independent dimers per unit cell. One of these molecules is disordered. The dimers consist of planar Al2C2‐skeletons with Al–C–Al bridging bonds of 212,9(2) and 221,2(2) pm, respectively, and with intramolecular C–H…Al contacts of 202(2) pm. |
