U. Thewalt et T. Wohrle, AN IONIC TI-IV FULVALENE COMPLEX - [[CPTI (H-2)] (C10H8,O)](2-)(2)CENTER-DOT-1() (SO3CF3)2THF/, Journal of organometallic chemistry, 506(1-2), 1996, pp. 331-335
The air-stable compound [CpTi(H2O)](2)(C10H8,O)(2+)(SO3CF3-)(2) . 1/2T
HF (5 . 1/2THF) is the first example of an ionic titanium-fulvalene co
mplex. It can be prepared from dinuclear 'titanocene', tifluoromethane
sulphonic acid and small amounts of water. The structure has been conf
irmed by X-ray crystallography. Space group and lattice constants are:
<P(1)over bar>; a=12.930(3), b=15.214(3),c=15.710(8) Angstrom alpha=8
5.87(2), beta=83.97(2), gamma=72.66(2)degrees; Z=4.
