Abstract

2-Phenoxybenzenesulfonamide, C12H11NO3S, (I), crystallizes in space group P (1) over bar with Z'=4, but the structure closely mimics the monoclinic space group P2(1)/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 R-2(2)(18) and R-6(6)(34) rings. N-Methyl-2-phenoxybenzenesulfonamide, C13H13NO3S, (II), crystallizes in space group P2(1) with Z'=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 spiro-fused R-2(2)(12) rings, and these chains are linked into sheets by a single C-H...pi(arene) hydrogen bond.
