Abstract
In 5-Chloro-3-methyl-1-phenyl-4-pyrazolesulphonamide, the phenyl and pyrazole rings are planar making a dihedral angle of 54.4 (2) o . The molecular packing involves an intermolecular hydrogen bond: N(3)---N(2 i )=2.951 (8), N(2 i )---H'(N3)=1.987 (6) A, N(3)H'(N3)---N(2 i )=154.8 (4) o [symmetry operation: (i)1/2+x, 1/2-y, 1/2+z]
