Abstract: The molecular structure of the title compound, C₆H₅BF₂O₂, is essentially planar (mean deviation = 0.019 Å), indicating electronic delocalization between the dihydroxyboryl group and the aromatic ring. In the crystal structure, inversion dimers linked by two O-HO hydrogen bonds arise. An intramolecular O-HF hydrogen bond reinforces the conformation and the same H atom is also involved in an intermolecular O-HF link, leading to molecular sheets in the crystal.
