Abstract
The title compound, C10H14N2O3S, crystallized with two molecules (A and B) in the asymmetric unit. The terminal methyl group of the ethylsulfonamide moiety in molecule B is disordered over two sets of sites with an occupancy ratio of 0.61 (1):0.39 (1). Both molecules have L-shaped conformations. In molecule A, the dihedral angles between the benzene ring and its ethylsulfonamide and methylamide substituents are 83.5 (3) and 13.34 (18)°, respectively. Equivalent values for molecule B are 87.9 (3) and 6.32 (16)°, respectively. The C—S—N—C torsion angles are 66.5 (3)° for A and −64.4 (3)° for B, indicating similar twists about the S—N bonds, but in opposite senses. In the crystal, the A molecules are linked by pairs of Ns—H⋯O (s = sulfonamide) hydrogen bonds, generating inversion dimers containing R 2 2(8) rings, while the B molecules are linked by Ns—H⋯O hydrogen bonds into C(10) [100] chains. Finally, Na—H⋯O (a = amide) hydrogen bonds link the A-molecule dimers and B-molecule chains into a three-dimensional network.
