Crystal structure of ethyl 2-(3,5-difluorophenyl)quinoline-4-carboxylate

Abstract

In the title compound, C18H13F2NO2, the two rings of the quinoline system are fused almost coaxially, with a dihedral angle between their planes of 2.28 (8)°. The plane of the attached benzene ring is inclined to the plane of the quinoline system by 7.65 (7)°. The carboxylate group attached to the quinoline system is in an antiperiplanar conformation. There is a short intramolecular C—H...O contact involving the carbonyl group. In the crystal, molecules are linked via C—H...O hydrogen bonds, forming chains lying in the (1-10) plane.
