In the title adduct, 2C6H5NO3·C4H9NO, the morpholine ring adopts a chair conformation. The dihedral angle between the two nitro-phenol 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 mol-ecules of nitro-phenol. The crystal structure is stabilized by N-H⋯O, O-H⋯N and O-H⋯O hydrogen bonds and further consolidated by C...

In the title adduct, C6H5NO3·0.5C4H10N2, the piperazine ring possesses inversion symmetry and has a chair conformation. Its mean plane makes a dihedral angle of 65.45 (7)° with the 4-nitro-phenol ring. In the crystal, the piperazine ring is linked to two 4-nitro-phenol mol-ecules via O-H⋯N hydrogen bonds. The mol-ecules are also linked via bifurcated N-H⋯(O,O) hydrogen bonds involving the NO2 O...

The asymmetric unit of the title compound, C3H6N6·2C6H5NO3, contains one melamine and two 3-nitro-phenol mol-ecules. The mean planes of the 3-nitro-phenol mol-ecules are almost orthogonal to the plane of melamine, making dihedral angles of 82.77 (4) and 88.36 (5)°. In the crystal, mol-ecules are linked via O-H⋯N, N-H⋯N and N-H⋯O hydrogen bonds, forming a three-dimensional network. The crystal a...
