Ethyl 1-phenyl-2-[4-(trifluoro­meth­oxy)phen­yl]-1H-benzimidazole-5-carboxyl­ate

In the title compound, C₂₃H₁₇F₃N₂O₃, an intra­molecular C—H...F hydrogen bond generates an S(6) ring motif. The essentially planar 1H-benzimidazole ring system [maximum deviation = 0.021 (2) Å] forms dihedral angles of 25.00 (10) and 62.53 (11)° with the trifluoro­meth­oxy-substituted benzene and phenyl rings, respectively. The twist of the ethyl acetate group from the least-squares plane of the 1H-benzimidazole ring system is defined by a C(=O)—O—C—C torsion angle of 79.5 (3)°. In the crystal, mol­ecules are linked into a two-dimensional network parallel to the bc plane by weak C—H...N and C—H...O hydrogen bonds. Weak C—H...π inter­actions also observed.
