In the title compound, C14H11NO2, the benzene rings are inclined to each other with a dihedral angle between their mean planes of 8.42 (6)°. The nitro group is almost coplanar with the attached benzene ring but is rotated about the C-N bond by 5.84 (12)°. This redetermination results in a crystal structure with significantly higher precision than the original determination [Hertel & Romer (1931). Z. Kristallogr. 76, 467-469], and the intermolecular interactions have been established. In the crystal structure, molecules are linked by C-HO hydrogen bonds to generate C(5), C(13) and edge-fused R33(28) rings.
