The structure of 2-({[3-methyl-4-(2,2,2-trifluoroethoxy)-2-pyridinyl]methyl}sulfonyl)-1H-1,3-benzimidazole, C
16H
14N
3O
3F
3S, has been solved. The compound belongs to a monoclinic space group (P2
1/c) with cell parameters a = 8.8693(9), b = 23.369(2), c = 8.6141(8) Å , b = 104.68(1)° , V = 1727.2(3) Å
3, Z = 4. The final R and wR(F
2) values were 0.070 and 0.147, respectively. The title molecule has a ? Z? shape in the crystal structure. The fused benzimidazole moiety and the pyridine ring are nearly coplanar. The molecules are linked by N—H…N and C—H…O hydrogen bonds into chains of edge-fused R
(14), R
(8), and R
(18) rings along the c-axis. The crystal lattice is further strengthened by p —p -stacking interactions.
