In the title molecular salt, (C3H12N2)[CrO4], each chromate anion accepts six N—H...O and C—H...O hydrogen bonds from nearby propane-1,2-diammonium cations. Three of the four O atoms of the chromate anion accept these bonds; the remaining Cr—O bond length is notably shorter than the others. In the crystal, the anions and cations stack in layers lying parallel to (100): the hydrogen-bonding pattern leads to a three-dimensional network.

In the anion of the title hydrated molecular salt, C9H8N+·C8H4NO6−·H2O, the protonated carboxyl and nitro groups makes dihedral angles of 27.56 (5) and 6.86 (8)°, respectively, with the attached benzene ring, whereas the deprotonated carboxy group is almost orthogonal to it with a dihedral angle of 80.21 (1)°. In the crystal, the components are linked by O—H...O and N—H...O hydrogen bonds, generating [001] chains. The packing is consolidated by weak C—H...N and C—H...O interactions as well as aromatic π–π stacking [centroid-to-centroid distances: 3.7023 (8) & 3.6590 (9)Å] interactions, resulting in a three-dimensional network.

In the title molecular salt, C22H21FI+·CF3SO3−, the dihedral angle between the rings of the biphenyl group is 65.6 (1)°. The ring of the mesitylene group is inclined to the fluorobenzene ring at an angle of 86.1 (3)° and the C—I—C bond angle is 97.0 (2)°. In the crystal, extremely short I...O contacts of 2.862 (5) and 2.932 (5) Å occur, due to the strong electrostatic interactions between the I atom and two adjacent trifluoromethanesulfonate counter-ions. There are also C—H...F and C—H...π interactions present: together with the I...O bonds, these result in a three-dimensional network.

In the cation of the title solvated molecular salt, C12H14ClN4+·C14H8F3O2S−·C2H6OS [systematic name of the cation: 2,4-diamino-5-(4-chlorophenyl)-6-ethylpyrimidin-1-ium], the dihedral angle between the planes of the pyrimidinium and 4-chlorophenyl rings is 77.2 (5)°. In the anion, the planes of the benzene rings are twisted with respect to each other by 71.5 (5)°. Disorder was modelled for the dimethyl sulfoxide solvent molecule over two set of sites in a 0.7487 (13):0.2513 (13) ratio. In the crystal, the cations are linked by inversion-generated pairs of N—H...N hydrogen bonds, with anR22(8) graph-set motif. The cation donates two N—H...O hydrogen bonds to the anion, also generating anR22(8) loop. These interactions, along with cation–solvent N—H...O hydrogen bonds, and cation–anion C—H...F, solvent–anion C—H...O and C—H...F interactions, result in a three-dimensional network.
