2-Fluoro-anilinium N-(2-fluoro-phenyl)oxamate

Abstract

The crystal structure of the title salt, C(6)H(7)FN(+)·C(8)H(5)FNO(3) (-), exhibits intra-molecular N-H⋯O and C-H⋯O and inter-molecular N-H⋯O and N-H⋯F hydrogen-bond inter-actions, the intra-molecular hydrogen-bond inter-actions generating S(6) and S(5) ring motifs. The dihedral angles between the aromatic ring and the intra-molecular hydrogen-bonded rings in the anion are 2.97 (7) and 6.70 (5)°. The two aromatic rings of the title compound are oriented with a dihedral angle of 77.25 (9)°.
