Crystal structure of N-(1-allyl-3-chloro-1H-indazol-5-yl)-4-methylbenzenesulfonamide

Abstract

The 3-chloro-1H-indazole system in the title molecule, C17H16ClN3O2S, is almost planar, with the largest deviation from the mean plane being 0.029 (2) Å for one of the N atoms. This system is nearly perpendicular to the allyl chain, as indicated by the C—C—N—N torsion angle of −90.1 (6)° between them. The allyl group is split into two fragments, the major component has a site occupancy of 0.579 (7). The indazole system makes a dihedral angle of 47.53 (10)° with the plane through the benzene ring. In the crystal, molecules are connected by N—H...O and C—H...O hydrogen bonds, forming a three-dimensional network.
