In the anion of the title molecular salt, C6H9BNO2+·C7H4NO4−, the dihedral angles between the –COO2− and –CO2H groups and their attached ring are 4.02 (13) and 21.41 (10)°, respectively. The B atom in the cation adopts a syn–syn geometry and the dihedral angle between the –B(OH)2 group and its attached ring is 11.06 (5)°. In the crystal, O—H⋯O, N—H⋯O and N—H⋯N hydrogen bonds link the components into a three-dimensional network.
