Abstract: In the title adduct, 2C₆H₅NO₃·C₄H₉NO, the morpholine ring adopts a chair conformation. The dihedral angle between the two nitrophenol rings is 69.47 (9)°. The nitro groups attached to the benzene rings make dihedral angles of 3.37 (16) and 3.14 (13)° in the two molecules of nitrophenol. The crystal structure is stabilized by N-HO, O-HN and O-HO hydrogen bonds and further consolidated by C-HO interactions, resulting in a three-dimensional network.
