In the title compound, C21H23N3O4S·H2O, the methylsulfanyl group is disordered over two sets of sites with site-occupancy factors of 0.631 (11) and 0.369 (11). The dihydropyridine ring adopts an E4 conformation. In the crystal, classical O—HN, O—HO and N—HO hydrogen bonds, as well as C—HO and C—HS contacts, connect the molecules into a three-dimensional network.

The asymmetric unit of the title compound, C13H10F3NO3, contains two independent molecules with similar conformations. In the crystal, N—HO hydrogen bonds link alternating independent molecules into chains in [-110]. In the chain, the quinoline planes of the independent molecules are almost perpendicular to each other, forming a dihedral angle of 89.8 (1)°. π–π interactions between the aromatic rings of quinoline bicycles related by inversion centres [for two independent centrosymmetric dimers, the shortest centroid–centroid distances are 3.495 (1) and 3.603 (1) Å] link the hydrogen-bonded chains into layers parallel to (110). Weak C—HF and C—HO interactions further consolidate the crystal packing.

The title compound, C24H18BrF3N4O4, is a 1,2,3-triazole derivative featuring, among others, a quinoline-derived substituent. In the crystal, C—HO, C—HN and C—HF contacts connect the molecules into a three-dimensional network. The shortest centroid–centroid distance between two aromatic systems is 3.896 (2) Å and is found between the two different six-membered rings of the quinoline scaffold in neighbouring molecules.
