Abstract

In the title compound, C19H21N3O3S, the C—SO2—NH—C torsion angle is 66.20 (9)°. The dihedral angle between the benzene ring and the essentially planar indazole ring system [r.m.s. deviation = 0.0361 (1) Å] is 72.97 (6)°. The S atom has a distorted tetrahedral geometry [maximum deviation = O—S—O = 119.30 (6)°]. The crystal structure features inversion-related dimers linked by pairs of N—H⋯O hydrogen bonds. In addition, weak C—H⋯O interactions may stabilize the crystal packing.

Highlights

The crystal structure features inversionrelated dimers linked by pairs of N—H O hydrogen bonds
In former papers, we reported the crystal structures of N-(7-ethoxy-1H-indazol-4-yl)-4-methylbenzenesulfonamide (Abbassi et al, 2011a) and N-[7-ethoxy-1-(prop-2-en-1-yl)-1H-indazol-4-yl]-4-methylbenzenesulfonamide (Abbassi et al, 2011b)
R-factors based on F2 are statistically about twice as large as those based on F, and R- factors based on ALL data will be even larger
