- Abstract
New organotitanium fluorides [Hdmpy]+[ (C5Me4R)2Ti2F7] - (R = Me 4, Et 5, dmpy = 2,6-dimethylpyridine, lutidine) have been prepared from (C5Me4R)TiF3 and 2,6-dimethylpyridinež(HF)2. The compounds 4 and 5 react with La(CF3SO3)3 to give [La{(C5Me4R)2Ti2F7} 3] (R = Me 6, Et 7) containing the [(C5Me4R) 2Ti2F7- anion as a tetrafluorodentate ligand in the crystal structures of 4 and 7. The cation-anion pair is connected by a hydrogen bond in 4 and the all-fluorine environment of 12 fluorine atoms coordinated to a lanthanum ion is found in 7. Œ 2001 Elsevier Science Ltd.
