1-(5-Nitro-2-oxoindolin-3-ylidene)-4-o-tolylthiosemicarbazide methanol monosolvate

In the title compound, C16H13N5O3S center dot CH4O, the dihedral angle between the isatin unit and the 2-methylphenyl group is 41.81 (2)degrees and intramolecular N-H center dot center dot center dot O and N-H center dot center dot center dot N hydrogen bonds occur, generating S(6) and S(5) rings, respectively. In the crystal, polymeric chains arise as a result of N-H center dot center dot center dot O, O-H center dot center dot center dot S and C-H center dot center dot center dot O interactions.
