Abstract: The asymmetric unit of the title compound, C23H18N2O3S, contains two molecules with comparable geometries. In one molecule, the pyrazole ring forms dihedral angles of 61.65 (11), 47.88 (11) and 63.20 (14)° with the three benzene rings. The corresponding values for the other molecule are 77.19 (11), 43.55 (11) and 63.56 (15)°. In the crystal, both molecules are linked into inversion dimers by pairs of C-H...S hydrogen bonds, generating R22(14) loops in each case.
