Abstract
The title molecule, C11H15N3O2S, features a five-membered ring which is twisted about the middle CH2-CH2 bond. The benzene ring is inclined with respect to the imine residue [CN-N-C torsion angle = 165.4 (2)degrees]. Supramolecular layers in the bc plane are formed by hydrogen bonds between the amine H atoms and sulfonamide O and imine N atoms, as well as by a weak hydrazine H-atom intermolecular interaction with the second sulfonamide O atom.
