Abstract: The structures of N-fluoropyridinium trifluoromethanesulfonate, C₅H₅FN⁺·CF₃O₃S^-, (I), and 1-fluoro-2,4,6-trimethoxy-1,3,5-triazinium hexafluoroantimonate, (C₆H₉FN₃O₃)[SbF₆], (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) Å, respectively.

Formula: C₅H₅FN⁺·CF₃O₃S^- and (C₆H₉FN₃O₃)[SbF₆]
