2-fluoroanilinium N-(2-fluorophenyl)-oxamate

Abstract

The crystal structure of the title salt, C6H7FN+center dot C8H5FNO3-, exhibits intramolecular N-H center dot center dot center dot O and C-H center dot center dot center dot O and intermolecular N-H center dot center dot center dot O and N-H center dot center dot center dot F hydrogen-bond interactions, the intramolecular hydrogen-bond interactions generating S(6) and S(5) ring motifs. The dihedral angles between the aromatic ring and the intramolecular hydrogenbonded rings in the anion are 2.97 (7) and 6.70 (5)degrees. The two aromatic rings of the title compound are oriented with a dihedral angle of 77.25 (9)degrees.
