Abstract: The asymmetric unit of the title compound, C3H6N6·2C6H5NO3, 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...[pi] and [pi]-[pi] interactions [centroid-centroid distance = 3.9823 (9) Å].
