N-(6-Chloro-1-methyl-1H-imidazo[4,5-c]pyridin-4-yl)benzene­sulfonamide

The asymmetric unit of the title compound, C₁₃H₁₁ClN₄O₂S, contains two mol­ecules (A and B), in which the dihedral angles between the 1H-imidazo[4,5-c]pyridine system and terminal phenyl ring are 80.83 (10) and 62.34 (1)°. In the crystal, A–B dimers are linked by pairs of N—H...N hydrogen bonds, which generate R²₂(10) loops. The dimers are linked by C—H...O and C—H...Cl inter­actions, generating a three-dimensional network. Aromatic π–π stacking inter­actions [shortest centroid–centroid distance = 3.5211 (12) Å] are also observed.

1,1′,1′′,1′′′-(Oxydi­methane­tri­yl)tetra­kis­(4-fluoro­benzene)

In the title compound, C₂₆H₁₈F₄O₂, the dihedral angles between pairs of benzene rings linked to the same C atom are 80.55 (8) and 79.11 (7)°. The crystal packing features C—H...π inter­actions and shows stacking when viewed along the c axis.
