title: 4-(4-Fluoro-benzene-sulfonamido)-phenyl 4-fluoro-benzene-sulfonate.
abstract: In the title compound, C(18)H(13)F(2)NO(5)S(2), the complete mol-ecule is generated by a crystallographic inversion centre, and the O atom and the N-H group attached to the central ring are statistically disordered. The dihedral angle between the central and terminal benzene rings is 64.03 (6)°. In the crystal, N-H⋯O, C-H⋯F and C-H⋯O inter-actions link the mol-ecules into a three-dimensional network.
