In the title compound, C21H23NO4S, the dihedral angle between the naphthalene residue and the benzene ring is 7.66 (3)°. In the molecule, there are some short C—H...O interactions. In the crystal, the structure is stabilized by weak intra­molecular C—H...O hydrogen bonds and the crystal structure is stabilized by weak C—H...O, C—H...π and π–π [centroid–centroid distance = 3.710 (2) Å] inter­actions.

The asymmetric unit of title compound, C19H22INO, contains two independent mol­ecules. Classical intra­molecular O—H...N hydrogen bonds stabilize the mol­ecular structures. The crystal structure is stabilized by weak inter­molecular C—H...π and π–π [centroid–centroid = 3.8622 (18) Å] inter­actions. In both mol­ecules, the aromatic rings are nearly perpendicular to each other [dihedral angles = 84.26 (17) and 86.69 (15)°].

In the title adduct, 2C6H5NO3·C3H6N6·H2O, the melamine and the two independent nitrophenol molecules are essentially planar, with maximum deviations of 0.0294 (10), 0.0706 (12) and 0.0742 (12) Å, respectively. In the crystal, N—H...N, O—H...N, N—H...O and O—H...O hydrogen bonds link the components into a three-dimensional network. In addition, weak π–π inter­actions [centroid–centroid distances = 3.728 (3) and 3.749 (3) Å] are observed.
