Ethyl 1-(4-fluorobenzyl)-2-(4-methoxyphenyl)-1H-benzo[d]imidazole-5-carboxylate

Abstract

The title benzoimidazole derivative, C24H21FN2O3, is T-shaped, with the methoxyphenyl and fluorobenzyl rings inclined to the benzoimidazole ring system by 40.91 (8) and 86.04 (8)°, respectively, indicating that the fluorobenzyl ring system is nearly orthogonal to the benzoimidazole ring system. The fluorobenzyl and methoxyphenyl rings are inclined to one another by 78.90 (10)°. In the crystal, molecules are linked via two pairs of C—H...O hydrogen bonds, forming inversion dimers with R22(28) and R22(22) ring motifs. As a result of these hydrogen bonds, ribbons propagating along [010] are formed.
