Abstract:
in the title compound, C(16)H(15)N(2) (+)·PF(6) (-), 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-H⋯F hydrogen bonds. Furthermore, P-F⋯π inter-actions involving imidazolium rings are observed [F⋯π = 2.9857 (16), P⋯π = 4.1630 (16) Å, P-F⋯π = 127.92 (6)°].
