Abstract

In the title compound, C(7)H(8)BNO(3), the mol-ecule lies on an inversion center leading to a statistical disorder of the B(OH)(2) and CONH(2) groups. In the crystal structure, mol-ecules are linked by N-H⋯O and O-H⋯O hydrogen bonds, forming sheets parallel to the bc plane. The B(OH)(2) and CONH(2) groups are twisted out of the mean plane of the benzene ring by 23.9 (5) and 24.6 (6)°, respectively.
