P. Jiang

Abstract: in the title compound, C₁₆H₁₅N₂⁺·PF₆^-, a precursor of N-heterocyclic carbene, the phenyl and benzyl rings are twisted away from the central imidazolium ring system, making dihedral angles of 70.30 (8) and 32.03 (10)°, respectively. The crystal structure is stabilized by C-HF hydrogen bonds. Furthermore, P-F interactions involving imidazolium rings are observed [F = 2.9857 (16), P = 4.1630 (16) Å, P-F = 127.92 (6)°].
