چکیده
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.

In the title compound, C(21)H(21)FN(3)O(2)P, the NH and P(=O) groups of the C(=O)NHP(=O) fragment are in a syn arrangement with respect to each other, as are the two amide H atoms of the two CH(3)-4-C(6)H(4)-NH moieties. In the crystal, mol-ecules are linked through N-H⋯O(=P) and N-H⋯O(=C) hydrogen bonds, forming R(2) (2)(8) and R(2) (2)(12) rings, which are arranged in chains parallel to [010].
