چکیده
The structure of the title compound, C(15)H(14)N(2)O(2), an azo dye, displays a trans configuration with respect to the N=N bridge. The dihedral angle between the aromatic rings is 5.06 (8)°. The mol-ecular conformation is stabilized by a strong intra-molecular O-H⋯O hydrogen bond. In the crystal, inter-molecular C-H⋯O hydrogen bonds occur.

The title compound, C20H21N3O, has crystallographic mirror symmetry with all non-H atoms apart from the methyl C atom of the CMe2 group lying on the mirror plane. Mol-ecules are linked into planar sheets parallel to (010) by phen-yl-azo C-H⋯N and phen-yl-ethanone C-H⋯O inter-actions. Methyl C-H⋯π inter-actions provide crosslinking between the planes.
