| Summary: | The nine-membered fused-ring system of the title pyridazine derivative, C13H12N4O4S, is approximately planar (r.m.s. deviation 0.027 Å), and the benzene ring of the phenylsulfamide substituent is aligned at 43.5 (1)° to the fused-ring system. The amine group of the sulfonamide substituent forms an N—H...O hydrogen bond to the ketonic O atom of two neigboring molecules to generate a chain running along the c axis. |
