Abstract:
In the title compound, C(15)H(14)N(2)O(4), the dihedral angle between the two benzene rings is 4.1 (2)°. The mol-ecule adopts an E configuration with respect to the C=N bond. There are intra-molecular O-H⋯N and O-H⋯O hydrogen bonds in the mol-ecule. In the crystal structure, mol-ecules are linked through inter-molecular N-H⋯O and O-H⋯O hydrogen bonds, forming chains running along the c axis.
