The crystal structure of the title compound, (C6H7FN)2[CuCl4], consists of parallel two-dimensional perovskite-type layers of corner-sharing CuCl6 octahedra. These are bonded together via N—HCl hydrogen bonds from the 4-fluoroanilinium chains, which are almost perpendicular to the layers. The CuCl4 dianions have two short Cu—Cl bonds [2.2657 (15) and 2.2884 (13) Å] and two longer bonds [2.8868 (15) Å], giving highly Jahn–Teller-distorted CuCl6 octahedra. The Cu atoms are situated on crystallographic centers of inversion.

There are two independent molecules in the asymmetric unit of the title compound, C21H21NO2, which was synthesized by the one-pot reaction of 2-naphthol, morpholine and benzaldehyde. The dihedral angles between the naphthalene ring systems and the benzene rings are 84.03 (7) and 75.76 (8)° in the two molecules and an intramolecular O—HN hydrogen bond occurs in each independent molecule.

In the title melaminium salt, 2,4,6-triamino-1,3,5-triazin-1-ium iodide monohydrate, C3H7N6+·I−·H2O, the components are linked via N—HO, N—HN, O—HI and N—HI hydrogen bonds. All of the H atoms of the melaminium cation are involved in hydrogen bonds. The melaminium cations are interconnected by four N—HN hydrogen bonds, forming ribbons along [111]. The water molecules connected by N—HO hydrogen bonds also form part of these ribbons. The ribbons are interconnected by other hydrogen bonds (O—HI and N—HI), as well as by π–π interactions [centroid–centroid distance = 3.6597 (17) Å].

In the title hydrated salt, 2,4,6-triamino-1,3,5-triazin-1-ium perchlorate monohydrate, C3H7N6+·ClO4−·H2O, the constituents are linked via hydrogen bonds of the O—HO, N—HO, N—HN and N—HCl types. All the H atoms of the melaminium cation are involved in the hydrogen bonds. The melaminium residues are interconnected by four N—HN hydrogen bonds, forming chains parallel to (111). The ribbons are interconnected by other hydrogen bonds as well as by π–π interactions [centroid–centroid distance = 3.8097 (7) Å].
