Crystal structure of 4-benzamido-2-hydroxybenzoic acid
In the title compound, C(14)H(11)NO(4), the dihedral angle between the mean planes of the aromatic rings is 3.96 (12)° and an intramolecular O—H⋯O hydrogen bond closes an S(6) ring. A short intramolecular C—H⋯O contact is also seen. In the crystal, carboxylic acid inversion dimers linked by pair...

Sumario: | In the title compound, C(14)H(11)NO(4), the dihedral angle between the mean planes of the aromatic rings is 3.96 (12)° and an intramolecular O—H⋯O hydrogen bond closes an S(6) ring. A short intramolecular C—H⋯O contact is also seen. In the crystal, carboxylic acid inversion dimers linked by pairs of O—H⋯O hydrogen bonds generate R (2) (2)(8) loops. Conversely, the N—H group does not form a hydrogen bond. Aromatic π–π interactions exist at a centroid–centroid distance of 3.8423 (15) Å between the benzene rings. An extremely weak C—H⋯π interaction also is present. |
