Crystal structure of ethyl 2-(5-amino-1-benzenesulfonyl-3-oxo-2,3-dihydro-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 molecules to form layers parallel to the bc plane.
