The asymmetric unit of the title salt, C16H21N2O2+·PF6-, contains half of the whole ion pair, which has crystallographic mirror symmetry. Two F atoms related by the mirror plane are disordered over two sites of equal occupancy. The dihedral angle between the central ring and the furan ring is 59.3 ()°. In the crystal, the anions and cations are linked through C-HF interactions, forming a three-dimensional network.
N-heterocyclic carbene (NHC)-metal complexes have attracted much attention, particularly for their functions in catalytic reactions, see: Akkoç & Gök (2013); Arduengo et al. (1992); Bagherzadeh et al. (2012); Hermann (2002); Lee et al. (2013); Saba et al. (1991); Yigit et al. (2007); Özdemir et al. (2001); Çetinkaya et al. (1997). For bond-length data, see: Allen et al. (1987).
