Abstract: In the title Schiff base, C₁₈H₂₂N₄O, the hexahydropyrimidinyl ring adopts a chair conformation. The dihedral angle between the aromatic rings of the 4-(2-phenyldiazenyl)phenol unit is 15.7 (1)°. There is an intramolecular O-HN hydrogen bond between the hydroxyl group and an N atom of the hexahydropyimidinyl unit. Intermolecular N-HO and N-HN hydrogen bonds give rise to a layer structure.
