In the title compound, C16H16N42+·2Cl−·4H2O, the molecules and ions are linked through N—H...Cl, O—H...Cl, O—H...O and N—H...O hydrogen bonds, while π–π stacking interactions between benzimidazolium units [the centroid-to-centroid distances between stacking benzene rings are 3.635 (3) and 3.817 (3) Å, respectively] and an N—H...π interaction help to stabilize the crystal structure.

In the structure of the title compound, C15H18N2O3, the two benzene rings are linked by an ethereal chain, forming a non-coplanar structure. The crystal structure exhibits a layer formation. The structure displays N—H...O, N—H...N and O—H...N hydrogen bonding. [ABSTRACT FROM AUTHOR]

In the title compound, C24H26N44+·4Cl−·2H2O, the cation possesses a crystallographically imposed centre of symmetry. The crystal structure is stabilized by intermolecular N—H...Cl, N—H...O and O—H...Cl hydrogen bonds, and by π–π stacking interactions. [ABSTRACT FROM AUTHOR]

In the crystal structure of the title compound, C16H22N22+·-2Br-·2H2O, the organic cation exhibits an extended zigzag structure. The Br- anions link with the solvent water molecules by O—H⋯Br hydrogen bonding. π-π stacking is observed between nearly parallel pyridine rings of adjacent molecules, the centroid-to-centroid distance between these rings being 3.887 (6) Å.

The asymmetric unit of the title compound, C16H12O5·0.5H2O, contains two essentially identical independent molecules and a water molecule of crystallization. The five fused rings form a non-planar structure in each molecule. The pyran ring is in a half-chair conformation, while the furan ring and the dioxolane ring adopt envelope conformations. The three molecules are linked through O—H⋯O hydrogen bonds. The O—H⋯O hydrogen bonds, C—H⋯π interactions and π-π stacking [centroid-centroid distance 3.7522 (2) Å] help to stabilize the crystal structure. [ABSTRACT FROM AUTHOR]

In the crystal structure of the title compound, C16H16N2O6, the molecule is centrosymmetric. The two benzene rings are linked by a diether strand, forming a non-coplanar structure with a dihedral angle of 5.18 (12)° between the benzene ring and the central chain. The molecular packing is controlled by C—H⋯π interactions and π -π stacking, with a Cg1⋯ Cg1(1 - x, 1 - y, 1 - z) distance of 3.7687 (12) Å (Cg1 is the centroid of the benzene ring).

The crystal structure of the title compound, C22H32N2O2, contains two independent molecules, each of which is centrosymmetric. Each molecule, with benzene rings linked by a diether strand, is essentially planar except for H atoms. There are two N—H...O and one N—H...N hydrogen bonds. The molecular packing is also controlled by N—H...π and C—H...π interactions. [ABSTRACT FROM AUTHOR]

In the structure of the title compound, C14H24N2O2, the two benzene rings are linked by a 1,6-dioxyhexyl chain to form a centrosymmetric nonplanar structure, the dihedral angle between the two rings being 0.00 (9)°. The structure displays an intramolecular N—H...O hydrogen bond and the molecular packing is controlled by N—H...π and C—H...π interactions. [ABSTRACT FROM AUTHOR]
