| Popis: | The title salt, 2C16H15F3N3OS+·C6Cl2O42−, is composed of two independent cations of a lansoprazole {systematic name 2-([3-methyl-4-(2,2,2-trifluoroethoxy)pyridin-2-yl]methylsulfinyl)-1H-benzo[d]imidazole} intermediate and a dianion of chloranilic acid. In the cations of the lansoprazole intermediate, the dihedral angles between the least-squares planes of the pyridine and benzimidazole rings are 11.1 (6) and 13.1 (5)°, respectively. The dihedral angles between the mean plane of the benzene ring in the chloranilic acid dianion and the pryidine and benzimidazole rings of the two lansoprazole intermediate groups are 71.8 (1)/80.5 (7) and 74.2 (4)/74.8 (6)°. In addition to ionic bond interactions, the lansoprazole intermediate and chloranilic ions are connected by strong N—H...O hydrogen bonds, which produce a set of extended O—H...O—H...O—H chains along the b axis in the (011) plane. In addition, weak C—H...O, C—H...F, N—H...Cl and π–π [centroid–centroid distances = 3.5631 (15), 3.8187 (13), 3.7434 (17) and 3.842 (2) Å] intermolecular interactions are observed, which contribute to crystal packing stability. |
