The title compound, C17H7F8N3O, was obtained via the reaction of 1-azido-2,3,4,5,6-pentafluorobenzene with 4,4,4-trifluoro-1-(p-tolyl)butane-1,3-dione using triethylamine as a base catalyst and solvent. The dihedral angles between the pentafluorophenyl (A), triazole (B) and p-tolyl (C) rings are A/B = 62.3 (2), B/C = 43.9 (3) and A/C = 19.1 (3)°. In the crystal, the molecules are linked by C—H...F and C—H...O hydrogen bonds as well as by aromatic π–π stacking interactions into a three-dimensional network. To further analyse the intermolecular interactions, a Hirshfeld surface analysis was performed.

In the cation of the title salt, C9H12N3S+·Br−, the thiazolidine ring adopts an envelope conformation with the C atom adjacent to the phenyl ring as the flap. In the crystal, N—H...Br hydrogen bonds link the components into a three-dimensional network. Weak π–π stacking interactions between the phenyl rings of adjacent cations also contribute to the molecular packing.

The title compound, C17H18N2O3, is constructed from a benzodiazepine ring system linked to a pendant dihydropyran ring, where the benzene and pendant dihydropyran rings are oriented at a dihedral angle of 15.14 (4)°. Intramolecular N—HDiazp...ODhydpand C—HDiazp...ODhydp(Diazp = diazepine and Dhydp = dihydropyran) hydrogen bonds link the seven-membered diazepine ring to the pendant dihydropyran ring, enclosingS(6) ring motifs. In the crystal, N—HDiazp...ODhydphydrogen bonds link the molecules into infinite chains along [10\overline{1}]. These chains are further linkedviaC—HBnz...ODhydp, C—HDhydp...ODhydpand C—HMth...ODhydp(Bnz = benzene and Mth = methyl) hydrogen bonds, forming a three-dimensional network. The observed weak C—HDiazp... π interaction may further stabilize the structure. Hirshfeld surface analysis of the crystal structure indicates that the most important contributions for the crystal packing are from H...H (51.1%), H...C/C...H (25.3%) and H...O/O...H (20.3%) interactions. Hydrogen bonding and van der Waals interactions are the dominant interactions in the crystal packing.

The title compound, C11H9F3N4S, was synthesized from 2-(trifluoromethyl)aniline by a multi-step reaction. It crystallizes in the non-centrosymmetric space group Pna21, with one molecule in the asymmetric unit, and is constructed from a pair of aromatic rings [2-(trifluoromethyl)phenyl and tetrazole], which are twisted by 76.8 (1)° relative to each other because of significant steric hindrance of the trifluoromethyl group at the ortho position of the benzene ring. In the crystal, very weak C—H...N and C—H...F hydrogen bonds and aromatic π–π stacking interactions link the molecules into a three-dimensional network. To further analyse the intermolecular interactions, a Hirshfeld surface analysis, as well as interaction energy calculations, were performed.

In the title compound, C13H14N2O3, the dihydropyridazine ring (r.m.s. deviation = 0.166 Å) has a screw-boat conformation. The dihedral angle between its mean plane and the benzene ring is 0.77 (12)°. In the crystal, intermolecular O—H...O hydrogen bonds generate C(5) chains and N—H...O hydrogen bonds produce R 2 2(8) motifs. These types of interactions lead to the formation of layers parallel to (12\overline{1}). The three-dimensional network is achieved by C—H...O interactions, including R 2 4(8) motifs. Intermolecular interactions were additionally investigated using Hirshfeld surface analysis and two-dimensional fingerprint plots. The most significant contributions to the crystal packing are by H...H (43.3%), H...C/C...H (19.3%), H...O/H...O (22.6%), C...N/N...C (3.0%) and H...N/N...H (5.8%) contacts. C—H...π interactions and aromatic π–π stacking interactions are not observed.
