چکیده
The title salt, 2C(16)H(15)F(3)N(3)OS(+)·C(6)Cl(2)O(4) (2-), 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} inter-mediate and a dianion of chloranilic acid. In the cations of the lansoprazole inter-mediate, 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 inter-mediate groups are 71.8 (1)/80.5 (7) and 74.2 (4)/74.8 (6)°. In addition to ionic bond inter-actions, the lansoprazole inter-mediate 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] inter-molecular inter-actions are observed, which contribute to crystal packing stability.
