Banks, R. Eric published the artcileN-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, Safety of 1-Fluoropyridiniumtriflate, the publication is Acta Crystallographica, Section C: Crystal Structure Communications (2003), C59(4), m141-m143, database is CAplus and MEDLINE.
The crystal structures of N-fluoropyridinium trifluoromethanesulfonate (I) and 1-fluoro-2,4,6-trimethoxy-1,3,5-triazinium hexafluoroantimonate (II) were determined I is monoclinic, space group P21/c, with a 6.027(2), b 12.901(4), c 12.490(3) Å, β 103.96(3)°; Z = 4, dc = 1.742; R = 0.045, Rw(F2) = 0.149 for 1658 reflections. II is monoclinic, space group P21/n, with a 7.616(2), b 11.843(3), c 14.924(3) Å, β 97.43(2)°; Z = 4, dc = 2.119; R = 0.034, Rw(F2) = 0.071 for 2335 reflections. The N-F bond lengths in I, a known electrophilic fluorinating agent, and its novel analog II are 1.357(4) and 1.354(4) Å, resp.
