4-(3,5-Dimethyl-1H-pyrazol-1-yl)benzenesulfonamide

Abstract

The two aromatic rings of the title compound, C 11H 13N 3O 2S, are inclined at an angle of 47.81 (4)°. The N atom of the amino unit is pyramidally coordinated; one H atom interacts with the sulfamyl O atom of an adjacent molecule, forming a centrosymmetric hydrogenbonded dimer. The dimers are linked by N - H⋯N hydrogen bonds, generating a threedimensional network.
