Die Kristallstruktur von Diethylaluminiumhypersilanid, [(C2H5)2Al–Si{Si(CH3)3}3]2

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.

Reactions of fullerene C60 with organometallic azides

Reactions of fullerene C₆₀ with organometallic azides [Et₂AlN₃, EtAl(N₃)₂ and Bu₃SnN₃] led to novel 1-azido-2-alkylfullerenes. The structures of the products were confirmed by IR, ¹Н and ¹³C NMR spectroscopy and MALDI TOF mass spectrometry.
