4-Methyl-N′-(2-oxoindolin-3-ylidene)benzene-1-sulfonohydrazide

What is it about?

In the title compound, C15H13N3O3S, the C-S-N(H)-N linkage is non-planar, the torsion angle being -65.12 (13)° and the S atom showing a tetra­hedral environment. The compound has two almost planar fragments linked to the S atom: the isatin-derivative fragment [(C8H5NO)N-N(H)-] and the tolyl fragment [C7H7-] have maximum deviations from the mean plane through the non-H atoms of 0.0813 (13) and 0.0094 (16) Å, respectively, and make an inter­planar angle of 80.48 (3)°. In the crystal, mol­ecules are connected into inversion dimers via pairs of N-H...O hydrogen bonds. Additionally, the mol­ecular structure is stabilized by an intra­molecular N-H...O hydrogen bond.
