5-Fluoro­isophthalic acid

By Jin-Ling Mi, Le Chen and Ming-Yang He


In the crystal structure of the title compound, C8H5FO4, the complete molecule is generated by crystallographic twofold symmetry with two C atoms and the F atom lying on the axis. The mol­ecule is almost planar with the carboxyl group twisted with respect to the mean plane of the benzene ring by a dihedral angle of 2.01 (1)°. In the crystal, inter­molecular O—H⋯O hydrogen bonds and C—H⋯F inter­actions connect the mol­ecules into a two-dimensional supra­molecular array
