4-(3-Nitro-phen-yl)-1-(2-oxoindolin-3-yl-idene)thio-semicarbazide.

In the title compound, C(15)H(11)N(5)O(3)S, intra-molecular N-H⋯N hydrogen bonding forms an S(5) ring motif, whereas N-H⋯O and C-H⋯S inter-actions type complete S(6) ring motifs. The 2-oxoindoline and 3-methoxy-phenyl rings are almost planar, with r.m.s. deviations of 0.0178 and 0.0149 Å, respectively, and form a dihedral angle of 33.59 (3)°. In the crystal, mol-ecules are inter-linked through the nitro groups in an end-to-end fashion via N-H⋯O and C-H⋯O inter-actions.
