title: N-fluoropyridinium trifluoromethanesulfonate and 1-fluoro-2,4,6-trimethoxy-1,3,5-triazinium hexafluoroantimonate: the first experimental determination of the F-N+ bond length involving sp2 nitrogen.
abstract: The structures of N-fluoropyridinium trifluoromethanesulfonate, C(5)H(5)FN(+).CF(3)O(3)S(-), (I), and 1-fluoro-2,4,6-trimethoxy-1,3,5-triazinium hexafluoroantimonate, (C(6)H(9)FN(3)O(3))[SbF(6)], (II), are presented. The N-F bond lengths in (I), a well known electrophilic fluorinating agent, and its novel analogue, (II), are 1.357 (4) and 1.354 (4) A, respectively.
