2-Phenoxybenzenesulfonamide, C12H11NO3S, (I), crystallizes in space group P1 with Z′ = 4, but the structure closely mimics the monoclinic space group P21/b with Z′ = 2. The molecules of (I) are linked by a combination of N-H...O and C-H...O hydrogen bonds into two independent chains of centrosymmetric edge-fused R22(18) and R66(34) rings. N-Methyl-2-phenoxybenzenesulfonamide, C13H13NO 3S, (II), crystallizes in space group P21 with Zprime; = 1, and is an example of spontaneous resolution. The molecules are linked by N-H...O and C-H...O hydrogen bonds into chains of spirofused R 22(12) rings, and these chains are linked into sheets by a single C-H...π(arene) hydrogen bond.
