Abstract
New organotitanium fluorides [Hdmpy](+)[(C5Me4R)(2)Ti2F7](-) (R = Me 4, Et 5, dmpy = 2,6-dimethylpyridine, lutidine) have been prepared from (C5Me4R)T iF3 and 2,6-dimethyIpyridine . (HF)(2). The compounds 4 and 5 react with La (CF3SO3)(3) to give [La{(C5Me4R)(2)Ti2F7}(3)] (R = Me 6, Et 7) containing t he [(C5Me4R)(2)Ti2F7](-) anion as a tetrafluorodentate ligand in the crysta l structures of 4 and 7. The cation-anion pair is connected by a hydrogen b ond in 4 and the all-fluorine environment of 12 fluorine atoms coordinated to a lanthanum ion is found in 7. (C) 2001 Elsevier Science Ltd.
