Methyl 2,4-dihydroxy-5-(4-nitrobenzamido)benzoate

Abstract

In the title compound, C15H12N2O7, the dihedral angle between the aromatic rings is 4.58 (13)° and the nitro group is rotated from its attached ring by 18.07 (17)°. Intramolecular N - H⋯O and O - H⋯O hydrogen bonds generate S(5) and S(6) rings, respectively. In the crystal, molecules are linked by O - H⋯O hydrogen bonds, generating [001] C(7) chains. The chains are linked by C - H⋯O interactions, forming a three-dimensional network, which incorporates R 2 2(7) and R 2 2(10) loops.
