Abstract

In the title compound, C25H22ClN3O5S, the two N atoms in the pyrazole ring have a pyramidal environment, with the sums of the valence angles around them being 349.3 (2) and 357.5 (2)°. The phenyl ring is twisted by 50.97 (12)° from the pyrazole mean plane. In the crystal, pairs of weak C—H⋯O hydrogen bonds link the mol­ecules into inversion dimers.
