N-{4-[(2-Meth-oxy-phen-yl)sulfamo-yl]phen-yl}acetamide.

In the title compound, C(15)H(16)N(2)O(4)S, the S atom has a distorted tetra-hedral geometry [maximum deviation: O-S-O = 118.25 (7)°]. The two aromatic rings make a dihedral angle of 62.67 (10)° with each other. An intra-molecular N-H⋯O hydrogen bond forms an S(6) ring motif. In the crystal, mol-ecules form centrosymmetric dimers via pairwise N-H⋯O inter-actions, forming an R(2) (2)(8) ring motif, and these dimers are connected by N-H⋯O hydrogen bonds, generating a three-dimensional network. Furthermore, a weak C-H⋯π inter-action helps to reinforce the crystal structure. The O atom in the acetamide group is disordered over two positions with major and minor occupancies of 0.52 (5) and 0.48 (5), respectively.
