1-Ethyl-N′-[(E)-4-hydroxy­benzyl­idene]-7-methyl-4-oxo-1,4-dihydro-1,8-naphthyridine-3-carbohydrazide

In the crystal structure of the title compound, C(19)H(18)N(4)O(3), the fused-ring system is essentially planar [maximum deviation is 0.031 (2) Å] while the dihedral angle between the ring system and the benzene ring is 12.64 (6)°.The carbohydrazide H atom is involved in an intra­molecular N—H⋯O hyd...

description In the crystal structure of the title compound, C(19)H(18)N(4)O(3), the fused-ring system is essentially planar [maximum deviation is 0.031 (2) Å] while the dihedral angle between the ring system and the benzene ring is 12.64 (6)°.The carbohydrazide H atom is involved in an intra­molecular N—H⋯O hydrogen bond, forming a six-membered hydrogen-bonded ring. The mol­ecules arrange themselves into centrosymmetric dimers by means of inter­molecular O—H⋯O hydrogen bonds.
