4-(3,7-Dimethyl-4-oxo-4,5-dihydro­isoxazolo[4,5-d]pyridazin-5-yl)benzene­sulfonamide

The nine-membered fused-ring system of the title pyridazine derivative, C(13)H(12)N(4)O(4)S, 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 f...

description The nine-membered fused-ring system of the title pyridazine derivative, C(13)H(12)N(4)O(4)S, 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.
