1-Benzyl-3-(2-methoxyphenyl)imidazolium tetrafluoroborate

In the title compound, C17H17N2O+·BF4−, the central imidazolium ring makes dihedral angles of 74.58 (9) and 40.10 (6)° with the phenyl and 2-methoxyphenyl rings, respectively. In the crystal, a strong π–π interaction is observed between the imidazolium and 2-methoxyphenyl rings, with a centroid–centroid distance of 3.5115 (15) Å. In addition, C—H...F and C—H...O hydrogen bonds and C—H...π interactions involving the phenyl ring are observed
