Crystal structure of N′-[(1E)-1-(6-methyl-2,4-dioxo-3,4-di­hydro-2H-pyran-3-yl­idene)eth­yl]benzene­sulfono­hydrazide

In the title compound, C(14)H(14)N(2)O(5)S, the mol­ecule exists in the enamine (C=C—NH) tautomeric form. The hydrazone fragment derived from the 3-acetyl-4-hy­droxy-6-methyl-2H-pyran-2-one moiety is approximately planar, with a maximum deviation of 0.1291 (11) Å for the N atom bound to the S atom o...

description In the title compound, C(14)H(14)N(2)O(5)S, the mol­ecule exists in the enamine (C=C—NH) tautomeric form. The hydrazone fragment derived from the 3-acetyl-4-hy­droxy-6-methyl-2H-pyran-2-one moiety is approximately planar, with a maximum deviation of 0.1291 (11) Å for the N atom bound to the S atom of the benzensulfono­hydrazide group. The latter adopts a gauche conformation relative to the hydrazone N—N bond, with an N—N—S angle of 113.54 (10)°. There is an intra­molecular N—H⋯O=C hydrogen bond that stabilizes the tautomeric form. In the crystal, mol­ecules are linked by N—H⋯O=C hydrogen bonds into chains extending parallel to [100].
