Crystal structure of 4-[(E)-(4-nitro­benzyl­idene)amino]­phenol

The asymmetric unit of the title compound, C(13)H(10)N(2)O(3), contains four independent mol­ecules (I, II, III and IV). Mol­ecule IV shows whole-mol­ecule disorder over two sets of adjacent sites in a 0.669 (10):0.331 (10) ratio. The dihedral angles between the aromatic rings are 32.30 (13)° in mol­ecule I, 2.24 (14)° in II, 41.61 (13)° in III, 5.0 (5)° in IV (major component) and 10.2 (3)° in IV (minor component). In the crystal, mol­ecules are linked into layers lying parallel to (024) by C—H⋯O and O—H⋯O inter­actions. The layers inter­act by C—H⋯π and weak aromatic π–π stacking inter­actions [centroid–centroid distances = 3.8476 (16), 3.725 (3) and 3.733 (5) Å].
