Description:
In the title m-terphenyl derivative, C22H17NO4, the dihedral angles between the aromatic rings of the benzoic acid–acetophenone, acetophenone–benzamide and benzoic acid–benzamide units are 45.39 (8), 48.02 (8) and 42.93 (8)°, respectively. The carbamoyl and carboxyl groups are disordered with a refined occupancy ratio of 0.558 (15):0.442 (15). In the crystal, molecules are linked through O—H...O and N—H...O hydrogen bonds between terminal carboxyl and carbamoyl groups in a bidentate manner, and antiparallel helices are formed which extend along the b-axis direction.
