(Z)-3-[(2-Fluoroanilino)carbonyl]prop-2-enoic acid

Abstract

In the title molecule, C10H8FNO3, the dihedral angle between the fluorophenyl group and the essentially planar [within 0.064 (3) Å] COC=CCOOH unit, which has a Z configuration, is 19.99 (14)°. There is an intramolecular O—H...O bond in the molecule involving the acid –OH group and the adjacent carbonyl O atom. In the crystal, intermolecular N—H...O bonds lead to the formation of polymer chains propagating along [011].
