Abstract: 2-Phenoxybenzenesulfonamide, C₁₂H₁₁NO₃S, (I), crystallizes in space group P $\overline 1$ 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-HO and C-HO hydrogen bonds into two independent chains of centrosymmetric edge-fused R ${_2^2}$ (18) and R ${_6^6}$ (34) rings. N-Methyl-2-phenoxybenzenesulfonamide, C₁₃H₁₃NO₃S, (II), crystallizes in space group P2₁ with Z' = 1, and is an example of spontaneous resolution. The molecules are linked by N-HO and C-HO hydrogen bonds into chains of spiro-fused R ${_2^2}$ (12) rings, and these chains are linked into sheets by a single C-H [bold pi] (arene) hydrogen bond.

Formula: C₁₂H₁₁NO₃S and C₁₃H₁₃NO₃S
