Abstract
In the title compound, C15H13NO3S, the mol-ecular conformation is stable with the intra-molecular O-H⋯O hydrogen bond forming a S(7) ring motif. In the crystal, mol-ecules are connected by C-H⋯O hydrogen bonds, forming C(8) chains running along the a-axis direction. Cohesion of the packing is provided by weak van der Waals inter-actions between the chains. A Hirshfeld surface analysis was undertaken to investigate and qu-antify the inter-molecular inter-actions. The thio-phene ring is disordered in a 0.9466 (17):0.0534 (17) ratio over two positions rotated by 180°.

Abstract
The title mol-ecule, C18H26O4, consists of two symmetrical halves related by the inversion centre at the mid-point of the central -C-C- bond. The hexene ring adopts an envelope conformation. In the crystal, the mol-ecules are connected into dimers by C-H⋯O hydrogen bonds with R 2 2(8) ring motifs, forming zigzag ribbons along the b-axis direction. According to a Hirshfeld surface analysis, H⋯H (68.2%) and O⋯H/H⋯O (25.9%) inter-actions are the most significant contributors to the crystal packing. The contribution of some disordered solvent to the scattering was removed using the SQUEEZE routine [Spek (2015 ▸). Acta Cryst. C71, 9-18] in PLATON. The solvent contribution was not included in the reported mol-ecular weight and density.

Abstract
The asymmetric unit of the title compound, 2C31H28N2O4S·C2H6O, contains a parent mol-ecule and a half mol-ecule of ethanol solvent. The main compound stabilizes its mol-ecular conformation by forming a ring with an R 1 2(7) motif with the ethanol solvent mol-ecule. In the crystal, mol-ecules are connected by C-H⋯O and O-H⋯O hydrogen bonds, forming a three-dimensional network. In addition, C-H⋯π inter-actions also strengthen the mol-ecular packing.

Abstract
In the title salt, C15H12FN2O+·Cl-·H2O, the imidazo[1,2-a]pyridin-1-ium ring system of the cation is almostly planar [maximum deviaition = -0.047 (2) Å for the ring C atom with the attached arene ring] and forms a dihedral angle of 61.81 (6)° with the plane of the fluoro-phenyl ring. In the crystal, water mol-ecules form an R 2 4(8) motif parallel to the (100) plane by bonding with the chloride ions via O-H⋯Cl hydrogen bonds. The cations are connected along the b axis via N-H⋯O hydrogen bonds involving the O atoms of water mol-ecules, and C-H⋯O, C-H⋯Cl and π-π inter-actions [centroid-to-centroid distance = 3.6195 (8) Å] form layers parallel to the (100) plane. Furthermore, these layers are connected via π-π inter-actions [centroid-to-centroid distance = 3.8051 (9) Å] that further consolidate the crystal structure.

Abstract
The title compound, C11H3I3N4O4·C2H6O, crystallizes in the triclinic P space group with one independent mol-ecule and one ethanol solvent mol-ecule in the asymmetric unit. The benzene ring and the methyl-carbonohydrazonoyl dicyanide group of the main mol-ecule makes a dihedral angle of 57.91 (16)°. In the crystal, O-H⋯O and N-H⋯O hydrogen bonds link pairs of mol-ecules, forming dimers with R 2 2(14) motifs. These dimers are connected by O-H⋯O hydrogen bonds into chains along the a-axis direction, forming R 2 2(16) ring motifs. Further O-H⋯O inter-actions involving the ethanol solvent mol-ecule connect the chains into a three-dimensional network. In addition, C-I⋯π inter-actions are observed. The inter-molecular inter-actions in the crystal structure were qu-anti-fied and analysed using Hirshfeld surface analysis.

In the crystal structure of (I), the cations are linked by pairs of C-H⋯O hydrogen bonds, forming inversion dimers with an R 2 2(8) ring motif. These dimers also exhibit O-H⋯O hydrogen bonding. Dimerized cation pairs and anions are arranged in columns along the a axis. In the crystal of (II), the cations are linked by pairs of O-H⋯O and C-H⋯O hydrogen bonds, forming an R 4 4(14) ring motif. These groups of cations and the anions form individual columns along the a axis and jointly reside in planes roughly parallel to (011). In the crystal of (III), cations and anions also form columns parallel to the a axis, resulting in layers parallel to the (020) plane. Furthermore, the crystal structures of (I), (II) and (III) are consolidated by strong halogen (Br and/or I and/or Cl)⋯H and weak van der Waals inter-actions. In addition to the structural evaluation, a Hirshfeld surface analysis was carried out.

Abstract
In the title complex, [Ni(C6H6N3OS)2]·2CH3OH, the NiII atom is coordinated by the S and N atoms of two N'-[(Z)-(furan-2-yl)methyl-idene]carbamohydrazono-thioic acid ligands in a distorted square-planar geometry. The two mutual ligands bound to NiII are also connected by C-H⋯S inter-actions, while the H atoms of the NH2 group of the ligands form R 4 4(8) motifs with the O atoms of the solvent ethyl alcohol mol-ecules. At the same time, the OH groups of the solvent ethyl alcohol mol-ecules form parallel layers to the (011) plane by the O-H⋯N inter-actions with the ligand N atom that is not bonded to the NiII atom.. The layers are connected by van der Waals inter-actions. A Hirshfeld surface analysis indicates that the most important contacts are H⋯H (37.7%), C⋯H/H⋯C (14.6%), O⋯H/H⋯O (11.5%) and S⋯H/H⋯S (10.6%).

In the title compound, C23H17N3O9S2, C-H⋯O hydrogen bonds link adjacent mol-ecules in a three-dimensional network, while π-π stacking inter-actions, with centroid-centroid distances of 3.8745 (9) Å, between the furan and an arene ring of one of the two (3-nitro-phen-yl)sulfonyl groups, result in chains parallel to the a axis. The Hirshfeld surface analysis indicates that O⋯H/H⋯O (40.1%), H⋯H (27.5%) and C⋯H/H⋯C (12.4%) inter-actions are the most significant contributors to the crystal packing.

Abstract
The title compound, 2C12H10N6·C3H7NO, crystallizes as a racemate in the monoclinic P21/c space group with two independent mol-ecules (I and II) and one di-methyl-formamide solvent mol-ecule in the asymmetric unit. Both mol-ecules (I and II) have chiral centers at the carbon atoms where the triazine rings of mol-ecules I and II are attached to the phenyl ring. In the crystal, mol-ecules I and II are linked by inter-molecular N-H⋯N, N-H⋯O and C-H⋯N hydrogen bonds through the solvent di-methyl-formamide mol-ecule into layers parallel to (001). In addition, C-H⋯π inter-actions also connect adjacent mol-ecules into layers parallel to (001). The stability of the mol-ecular packing is ensured by van der Waals inter-actions between the layers. The Hirshfeld surface analysis indicates that N⋯H/H⋯N (38.3% for I; 35.0% for II), H⋯H (28.2% for I; 27.0% for II) and C⋯H/H⋯C (23.4% for I; 26.3% for II) inter-actions are the most significant contributors to the crystal packing.

Abstract
In the crystal, strong C—H⋯O and N—H⋯N hydrogen bonds form dimers with (14) and (12) ring motifs between adjacent molecules along the c-axis direction. Intermolecular N—H⋯O and C—H⋯O hydrogen bonds connect these dimers to form a three-dimensional network. In addition, C—H⋯π interactions and π–π stacking interactions help to stabilize the packing. The central tetrahydropyridine ring of the title compound, C19H17N3O2, adopts a screw-boat conformation. In the crystal, strong C—H⋯O and N—H⋯N hydrogen bonds form dimers with R22(14) and R22(12) ring motifs, respectively, between consecutive molecules along the c-axis direction. Intermolecular N—H⋯O and C—H⋯O hydrogen bonds connect these dimers, forming a three-dimensional network. C—H⋯π interactions and π–π stacking interactions contribute to the stabilization of the molecular packing. A Hirshfeld surface analysis indicates that the contributions from the most prevalent interactions are H⋯H (47.1%), C⋯H/H⋯C (20.9%), O⋯H/H⋯O (15.3%) and N⋯H/H⋯N (11.4%).

Abstract
In the crystal, N—H⋯O hydrogen bonds link the molecules into dimers with an (16) ring motif. Further N—H⋯O and N—H⋯N hydrogen bonds connect the dimers into chains along the c-axis direction. C—Br⋯π and C=O⋯π interactions stabilize the molecular packing, resulting in a three-dimensional network. The crystal structure of the title compound, C20H16BrN3O2, was determined using an inversion twin. Its asymmetric unit comprises two crystallographically independent molecules (A and B) being the stereoisomers. Both molecules are linked by pairs of N—H⋯O hydrogen bonds, forming a dimer with an R22(16) ring motif. The dimers are connected by further N—H⋯O and N—H⋯N hydrogen bonds, forming chains along the c-axis direction·C—Br⋯π interactions between these chains contribute to the stabilization of the molecular packing. Hirshfeld surface analysis showed that the most important contributions to the crystal packing are from H⋯H, C⋯H/H⋯C, O⋯H/H⋯O, Br⋯H/H⋯Br and N⋯H/H⋯N interactions.
