The packing of the title compound, C12H9N7·H2O, is dominated by hydrogen bonding and π-stacking. Layers parallel to [010] are established by hydrogen bonds involving all amine donor functions and one of the water donor functions, while the remaining water donor function enables the stacking of the layers along [10-1], which is accompanied by π-stacking. In the molecule, the plane of the central...

In the title compound, C(21)H(18)O(5)S(2), the two sulfur-bound phenyl rings lie on opposite sides of the meth-oxy-phenyl group, making dihedral angles of 77.58 (8) and 87.45 (8)°with it. The dihedral angle between the sulfur-bound phenyl rings is 57.31 (8)°. In the crystal, π-π stacking is observed between the two sulfur-bound phenyl rings, with a centroid-centroid distance of 3.878 (1) Å and ...

The molecular conformation of the title compound, C(25)H(15)NO(8), is stabilized by strong intramolecular O-H⋯O hydrogen bonds, resulting in the formation of S(1) (1)(7) ring motifs. In the crystal, π-π stacking inter-actions are observed between adjacent nitrobenzene and pyranone rings with a centroid-centroid distance of 3.513 (12) Å. The dihedral angles between the nitrobenzene ring and the ...

The title compound, C(9)H(7)IN(+)·Cl(-)·2H(2)O, was obtained during the synthesis of 8-iodo-quinoline from 8-amino-quinoline using the Sandmeyer reaction. The 8-iodo-quinolinium ion is almost planar. Solvent water mol-ecules and chloride ions form a hydrogen-bonded chain along the c axis via O-H⋯Cl links. The 8-iodo-quinolinium ions, which are packed along the c axis with cationic aromatic π-π ...

The title compound, C(22)H(16)ClNO(4), adopts a conformation in which the phenyl ring plane forms similar dihedral angles with the nitro-benzoate C(6) ring [76.97 (8)°] and the chloro-phenyl group [76.95 (8)°]; the dihedral angle between the chloro-phenyl and nitro-benzoate rings is 66.43 (8)°. In the crystal, π-π stacking is observed between the latter two planes, with a dihedral angle of 1.79...

The asymmetric unit of the title compound, C(23)H(17)F(3)N(2)O(2), contains two mol-ecules. In one of the mol-ecules, the phenyl and triflouromethyl-substituted benzene rings form dihedral angles of 52.05 (8) and 33.70 (8)°, respectively, with the benzimidazole ring system, while the dihedral angle between them is 58.24 (10)°. The corresponding values in the other mol-ecule are 58.40 (8), 25.90...
