Abstract
Abstract The complexes of [Pr{(C5Me5)2Ti2F7}3] 2 and [Nd{(C5Me5)2Ti2F7}3] 3 were obtained by the reaction of [Hdmpy]+[(C5Me5)2Ti2F7]− 1 (dmpy=2,6–dimethylpyridine, C5H3NMe2), with praseodymium(III) and neodymium(III) trifluoromethanesulfonate. The X–ray crystal structures of 2 and 3 exhibit a fluorine environment of 12 at the praseodymium and of 11 at the neodymium with [(C5Me5)2Ti2F7]− acting as well as a tetra- and as a three-fluorodentate ligand. Both complexes retained their structures in solution. Complex 2 is the first molecular compound containing PrF bonds.
