2,5-Diphenyl-2,5,6,8-tetrahydro-1,2,4-triazolo[3,4-c][1,4]oxazin-4-ium hexafluoridophosphate

Abstract

The title compound, C17H16N3O+·PF6−, is a chiral bicyclic 1,2,4-triazolium salt. In the crystal packing, C—H...O and C—H...F hydrogen bonds and P—F...π contacts [4.078 (11)–4.163 (11) Å, involving the triazolium ring] play an important role in enhancing the stability of the crystal structure.
