✦ Synopsis

The Crystal Structure of Diethylaluminium Hypersilanide

AlCl] 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 Al 2 C 2 -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.

The title compound has been prepared in good yield by the reaction of [Me 2 GaOMe] 3 (Me = CH 3 ) with HP(SiMe 3 ) 2 in toluene (ratio 1 : 1,1) and purified by crystallization from pentane or toluene, respectively. This organogallium compound forms (Ga±P) 3 ring skeletons with one Ga±P(SiMe 3 ) 2 ±G
