5′-Amino-2-oxo-2′,3′-dihydrospiro[indoline-3,7′-thieno[3,2-b]pyran]-6′-carbonitrile 1′,1′-dioxide

In the title compound, C15H11N3O4S, the dihedral angle between the mean planes of the dihydroindol-2-one (r.m.s. deviation = 0.015 Å) and dihydrothieno[3,2-b]pyran (r.m.s. deviation = 0.011 Å) ring systems is 89.53 (3)°. The crytal packing is consolidated by intermolecular N—H...O and N—H...N hydrogen bonds, which link the molecules into a two-dimensional network into sheets lying parallel to (100).
