Crystal structure of ethyl 2-(5-amino-1-benzene-sulfonyl-3-oxo-2,3-di-hydro-1H-pyrazol-2-yl)acetate.

ABSTRACT: In the title compound, C13H15N3O5S, the two rings face each other in a 'V' form at the S atom, with one N-H?O=S and one C-H?O=S contact from the pyrazolyl substituents to the sulfonyl group. Two classical hydrogen bonds from the amine group, one of the form N-H?O=S and one N-H?O=Coxo, link the mol-ecules to form layers parallel to the bc plane.
