Abstract

The asymmetric unit of the title compound, C(22)H(19)FN(2)O, contains two independent mol-ecules. The planar benzimidazole ring systems are oriented with respect to the phen-yl/fluoro-benzene rings at dihedral angles of 31.10 (4)/45.17 (5) and 45.52 (5)/68.63 (5)°, respectively, for the two mol-ecules. In the crystal structure, inter-molecular C-H⋯N and inter-molecular C-H⋯N and C-H⋯F hydrogen bonds link the mol-ecules into a three-dimensional network. There are C-H⋯π contacts between the benzimidazole and fluoro-benzene rings and a π-π contact between the benzimidazole and phenyl ring systems [centroid-centroid distance = 4.575 (1) Å].
