摘要：

[Et2Al-Hsi](2) (Et = C2H5, Hsi = Si(SiMe3)(3)), pre pared from [Et2AlCl](2) and equimolar amounts of base-free Li-Hsi in n-pentane, crystallizes in the triclinic space group P (1) over bar 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 a intramolecular C-H . . . Al contacts of 202(2) pm.
