The asymmetric unit of the title salt, C7H10N+·C8H5O4−, consists of two 3-methylphenylammonium cations and two hydrogen phthalate anions. There are strong intramolecular O—HO hydrogen bonds in the virtually planar (r.m.s. deviations = 0.054 Å) phthalate anions. In the crystal, the cations and anions are connected via an extensive sytem of N—HO hydrogen bonds into a corrugated layer extended parallel to (001).

In the title molecular salt, C4H10NO+·C4H5O6−, the morpholinium cation adopts a chair conformation. The conformation of the C—C—C—C backbone of the monotartrate anion is close to anti [torsion angle = 173.18 (17)°], which is supported by two intramolecular O—HO hydrogen bonds. In the crystal, the components are linked by N—H—O and O—H—O hydrogen bonds, generating (001) sheets.

The asymmetric unit of the title compound, C8H6F3N2+·0.5C10H6O6S22−, consists of one 2-trifluoromethyl-1H-benzimidazol-3-ium cation and a half naphthalene-1,5-disulfate anion, which are linked by an N—HO hydrogen bond. The anion sits across a centre of symmetry. The atoms of the benzimidazole ring are nearly coplanar (r.m.s. deviation of the fitted atoms = 0.0085 Å) and the triflouromethyl group lies out of this plane. In the crystal, the cations are linked to adjacent anions by N—HO hydrogen bonds, forming a ladder structure parallel to the a axis in which the anions form the rungs. Adjacent ladders are linked by weak C—HO interactions, forming sheets parallel to the ac plane.

The asymmetric unit of the title compound, C8H6F3N2+·BF4−·C8H5F3N2·H2O, consists of two 2-trifluoromethylbenzimidazole molecules, each of which is protonated on a 50% basis, one tetrafluoroborate anion and a water molecule. The two 2-trifluoromethylbenzimidazole molecules thus exist as half-neutral half-cation entities. They are linked by N—HN hydrogen bonds involving the half-occupancy hydrogens in each molecule. The F atoms of one of the trifluoromethyl groups are disordered over two sets of sites [in a 0.518 (14):0.482 (14) ratio], as are the F atoms of the tetrafluoroborate anion [0.507 (14):0.493 (14) ratio]. The water molecule is linked to one of the 2-trifluoromethylbenzimidazole molecules via an N—HO hydrogen bond.
