The asymmetric unit of the title salt [systematic name: 1-benzhydryl-4-cinnamylpiperazine-1,4-diium bis­(p-toluene­sulfonate) dihydrate], C26H30N22+·2C7H7O3S·2H2O, consists of a diprotonated cinnarizinium cation hydrogen bonded through two water mol­ecules to two independent p-toluene­sulfonate anions, one which is disordered over two sets of sites in a 0.793 (3):0.207 (3) ratio. In the cation, the piperazine ring adopts a chair configuration and contains two positively charged N atoms with quarternery character. The dihedral angle between the two benzene rings in the benzhydr­yl group is 71.8 (1)°. The benzene ring flanked opposite the piperazine ring is twisted by 75.9 (9) and 8.8 (3)° from these two benzene rings. In the crystal, the [N—H...Owater—H...O([pdbond]S)]2 hydrogen-bonded asymmetric unit is connected by further O—H...O hydrogen bonds linking the components into chains along [100].

In the title compound, C11H8Cl2N2OS, the mean plane of the dichloro­phenyl ring is twisted by 79.7 (7)° from that of the thia­zole ring. In the crystal, molecules are linked via pairs of N—H...N hydrogen bonds, forming inversion dimers which stack along the a-axis direction.

The mol­ecule of the title compound, C12H14N4O, is roughly planar, with a dihedral angle of 8.0 (8)° between the benzene and pyrazole rings, and an intra­molecular N—H...O hydrogen bond forms an S(6) ring motif. In the crystal, mol­ecules are linked into an inversion dimer by a pair of N—H...O hydrogen bonds, which form an R22(8) ring motif.

Three independent mol­ecules comprise the asymmetric unit of the title compound, C10H19N5O2, (systematic name: 4-amino-N-tert-butyl-3-isopropyl-5-oxo-4,5-dihydro-1H-1,2,4-triazole-1-carboxamide) . In all three mol­ecules, the triazole ring and the carboxamide group are almost coplanar [within 4.0–5.9 (9)°], particularly because of the formation of an intra­molecular N—H...O hydrogen bond. On other hand, the orientation of the isopropyl group varies significantly from mol­ecule to mol­ecule. The crystal packing is dominated by N—H...O and N—H...N hydrogen bonds, which connect the mol­ecules into infinite chains along [010].
