Bis(2-{[3-methyl-4-(2,2,2-trifluoro-eth-oxy)-2-pyrid-yl]methyl-sulfan-yl}-1H,3H-benzimidazolium) 2,5-dichloro-3,6-dioxocyclo-hexa-1,4-diene-1,4-diolate.

ABSTRACT: 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 ?-? [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.
