The asymmetric unit of the title thiazole derivative containing a sulfonylhydrazinic moiety, C9H8ClN3O3S2·H2O, consists of two independent molecules and two water molecules. The central parts of the molecules are twisted as both the molecules are bent at both the S and N atoms. In the crystal, N—H...N, N—H...O, C—H...O and O—H...O hydrogen-bonding interactions connect the molecules, forming layers parallel to the ab plane. Two-dimensional fingerprint plots associated with the Hirshfeld surface show that the largest contributions to the crystal packing come from O...H/H...O (32.9%) and H...H (22.6%) interactions.

The asymmetric unit of the title compound, C16H20N2O2, consists of two independent molecules differing slightly in the conformations of the seven-membered rings and the butyl substituents, where the benzene rings are oriented at a dihedral angle of 34.56 (3)°. In the crystal, pairwise intermolecular C—H...O and complementary intramolecular C—H...O hydrogen bonds form twisted strips extending parallel to (012). These strips are connected into layers parallel to (111) by additional intermolecular C—H...O hydrogen bonds. The layers are further joined by C—H...π interactions.

Molecular Layers

The asymmetric unit of the title compound, C15H12Br2F3NO2, consists of two crystallographically independent molecules. In both molecules, the pyrrolidine and tetrahydrofuran rings adopt an envelope conformation. In the crystal, molecule pairs generate centrosymmetric rings with R 2 2(8) motifs linked by C—H...O hydrogen bonds. These pairs of molecules form a tetrameric supramolecular motif, leading to molecular layers parallel to the (100) plane by C—H...π and C—Br...π interactions. Interlayer van der Waals and interhalogen interactions stabilize molecular packing. The F atoms of the CF3 groups of both molecules are disordered over two sets of sites with refined site occupancies of 0.60 (3)/0.40 (3) and 0.640 (15)/0.360 (15). The most important contributions to the surface contacts of both molecules are from H...H (23.8 and 22.4%), Br...H/H...Br (18.3 and 12.3%), O...H/H...O (14.3 and 9.7%) and F...H/H...F (10.4 and 19.1%) interactions, as concluded from a Hirshfeld surface analysis.

In the title compound, C15H10BrFO, the molecular structure consists of a 3-bromophenyl ring and a 4-fluorophenyl ring linked via a prop-2-en-1-one spacer. The 3-bromophenyl and 4-fluorophenyl rings make a dihedral angle of 48.90 (15)°. The molecule has an E configuration about the C=C bond and the carbonyl group is syn with respect to the C=C bond. In the crystal, molecules are linked by C—H...π interactions between the bromophenyl and fluorophenyl rings of molecules, resulting in a two-dimensional layered structure parallel to the ab plane. The molecular packing is stabilized by weak Br...H and F...H contacts, one of which is on the one side of each layer, and the second is on the other. The intermolecular interactions in the crystal packing were further analysed using Hirshfeld surface analysis, which indicates that the most significant contacts are Cl...H/H...Cl (20.8%), followed by C...H/H...C (31.1%), H...H (21.7%), Br...H/H...Br (14.2%), F...H/H...F (9.8%), O...H/H...O (9.7%).

The title compound, C16H11ClN2O2, was obtained by diazotization of 2-amino-4-chlorophenol followed by a coupling reaction with β-naphthol. There are two molecules (A and B) in the asymmetric unit. The crystal structure features only one type of intermolecular interaction, that is strong hydrogen bonds involving the hydroxyl group. The naphthol and phenol fragments attached to the C=N—N— moiety exhibit an s-trans conformation. In addition, those fragments are almost coplanar, subtending a dihedral angle of 13.11 (2)° in molecule A and 10.35 (2)° in molecule B. A Hirshfeld surface analysis indicates that the most important contributions to the crystal packing are from H...H (32.1%), C...H/H...C (23.1%), Cl...H/H...Cl (15.2%), O...H/H...O (12.8%) and C...C (9%) contacts.
