The crystal structures of two N-(aryl-sulfon-yl)aryl-amides, namely N-(3-fluoro-benzo-yl)benzene-sulfonamide, C13H10FNO3S, (I), and N-(3-fluoro-benzo-yl)-4-methyl-benzene-sulfonamide, C14H12FNO3S, (II), are described and compared with related structures. The dihedral angle between the benzene rings is 82.73 (10)° in (I) compared to 72.60 (12)° in (II). In the crystal of (I), the mol-ecules are linked by C-H⋯O and C-H⋯π inter-actions, resulting in a three-dimensional grid-like architecture, while C-H⋯O inter-actions lead to one-dimensional ribbons in (II). The crystals of both (I) and (II) feature strong but non-structure-directing N-H⋯O hydrogen bonds with R 2 (2)(8) ring motifs. The structure of (I) also features π-π stacking inter-actions.
描述了两种N-(芳基磺酰基)芳基酰胺的晶体结构，即N-(3-氟苯甲酰基)苯磺酰胺，C₁₃H₁₀FNO₃S，(I)，和N-(3-氟苯甲酰基)-4-甲基苯磺酰胺，C₁₄H₁₂FNO₃S，(II)，并与相关结构进行了比较。(I)中苯环之间的二面角为82.73 (10)°，而(II)中为72.60 (12)°。在(I)的晶体中，分子通过C-H⋯O和C-H⋯π相互作用相连，形成三维网格状结构，而在(II)中C-H⋯O相互作用导致一维带状结构。(I)和(II)的晶体都具有强但非结构导向的N-H⋯O氢键，其具有R 2 (2)(8)环模式。(I)的结构还具有π-π堆积相互作用。
