2,3-Difluoro-4-formylphenylboronic acid.

The molecule of the title compound, 2,3-F(2)-4-(CHO)C(6)H(2)B(OH)(2) or C(7)H(5)BF(2)O(3), contains a formyl group coplanar with the benzene ring. The boronic acid group is twisted with respect to the benzene ring plane. The molecules are organized into infinite chains via intermolecular O-H...O hydrogen bonds. These chains are additionally connected via strong O-H...O hydrogen bonds, producing a folded layer structure perpendicular to the a axis. These layers are paired due to B...F interactions.
