3-Nitro­phenol–1,3,5-triazine-2,4,6-tri­amine (2/1)

The asymmetric unit of the title compound, C(3)H(6)N(6)·2C(6)H(5)NO(3), contains one melamine and two 3-nitro­phenol mol­ecules. The mean planes of the 3-nitro­phenol mol­ecules are almost orthogonal to the plane of melamine, making dihedral angles of 82.77 (4) and 88.36 (5)°. In the crystal, mol­ecules are linked via O—H⋯N, N—H⋯N and N—H⋯O hydrogen bonds, forming a three-dimensional network. The crystal also features weak C—H⋯π and π–π inter­actions [centroid–centroid distance = 3.9823 (9) Å].
