Abstract
The asymmetric unit of the title compound, C15H14ClN3O2S, contains two independent molecules showing different conformations: in one molecule, the indazole ring system makes a dihedral angle of 51.5 (1)° with the benzene ring whereas in the other, the indazole unit is almost perpendicular to the benzene ring [dihedral angle 77.7 (1)°]. In the crystal, the molecules are linked by N—H⋯N and N—H⋯O hydrogen bonds, forming a set of four molecules linked in pairs about an inversion centre.
