“…In contrast, the configuration at the silene-carbon 2 Si C(OSiMe 3 )Ad (1.764 ; Ad 1-adamantyl) [9] and (Me 3 Si) 2 Si Ad' (1.741 ; Ad' 2-adamantylidene) [10] are similar to the value obtained for 7. The SiC distance in 7 is slightly longer than that reported for the uncomplexed stable silene Me 2 SiC(SiMe 3 )(SiMetBu 2 ) (1.702 ),…”

“…This smokes and decomposes spontaneously in air but survives unchanged stored under argon at room temperature for over 4 years. The results of an X-ray crystal structure determination have been briefly reported (Brook, Nyburg, Abdesaken, Gutekunst, Gutekunst, Kallury, Poon, Chang & Wong-Ng, 1982). The detailed results are presented here together with a discussion of the results of two structure analyses of silenes prepared since our original report appeared.…”

Synthesis and Structure of Lithium Tris (trimethylsilyl) silanide . 1,5 DME Abstract. Lithium tris(trimethylsilyl}silanide' 1,5 DME 2a synthesized from tetrakis(trimethylsilyl)silane 1 [6] and methyllithium in 1,2-dimethoxyethane 1 ), crystaIlizes in the monocIinic space group P2 1 /c with following dimensions of the unit cell determined at a temperature of measurement of -120 ± 2°C: a = 1072.9(3); b = 1408.3(4}; c = 1775.1(5} pm; ß = 107.74(2)°; 4 formula units (Z = 2). An X-ray structure determination (R w = 0.040) shows the compound to be built up from two [lithium tris(trimethylsilyl)silanide] moieties which are connected via a bridging DME moleeule. Two remaining sites of each four-coordinate lithium atom are occupied by a chelating DME ligand. The Li-Si distance of 263 pm is considerably longer than the sum oi covalent radii; further charactcristic mean bond lengths and angles are: Si-Si 234, Li-O 200, O-C 144, 0···0 (bite) 2G4pm; Si-Si--Si 104°, Li--Si-Si 107° to 126°; O-Li-O (inside the chelate ring) 83°. Unfortunately, di(tert-butyl)bis(trimethylsilyl)silane 17 prepared from di(tert-bntyl)dichlorsilane 15, chlorotrimethylsilane and lithium, does not react with alkyllithinm compounds to give the analogons silanide.
