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 also features weak C-H⋯π and π-π inter-actions [centroid-centroid distance = 3.9823 (9) Å].
标题化合物C₃H₆N₆·2C₆H₅NO₃的不对称单元包含一个三聚氰胺分子和两个3-硝基苯酚分子。3-硝基苯酚分子的平均平面与三聚氰胺平面几乎正交，二面角分别为82.77 (4)°和88.36 (5)°。在晶体中，分子通过O-H⋯N、N-H⋯N和N-H⋯O氢键相连，形成三维网络。该晶体还具有弱的C-H⋯π和π-π相互作用[质心-质心距离 = 3.9823 (9) Å]。
