(E)-N′-(3-Eth­oxy-4-hy­droxy­benzyl­idene)-4-meth­oxy­benzohydrazide

摘要

In the mol­ecule of the title benzohydrazide derivative, C17H18N2O4, the dihedral angle between the benzene rings is 6.86 (11)°. The meth­oxy group of the 4-meth­oxy­phenyl fragment deviates slightly [Cmethyl—O—C—C = 10.0 (4)°] with respect to the benzene ring, whereas the eth­oxy group of the 3-eth­oxy-4-hy­droxy­phenyl fragment is is almost coplanar [C—O—C—Cmethyl = 178.5 (2)°]. In the crystal, mol­ecules are linked by N—H⋯O, O—H⋯O and C—H⋯O hydrogen bonds into a two-dimensional network parallel to the ab plane. C—H⋯π inter­actions and C⋯O [2.980 (3) Å] short contacts are also observed.
