(E)-Ethyl N′-[1-(2-hydroxy­phen­yl)ethyl­idene]hydrazinecarboxyl­ate

Abstract

In the mol­ecule of the title compound, C11H14N2O3, the dihedral angle between the benzene ring and the hydrazinecarboxyl­ate mean plane is 3.65 (12)°. Intra­molecular C—H⋯N and O—H⋯N hydrogen bonds result in the formation of a nearly planar six-membered ring, which is oriented at a dihedral angle of 2.38 (3)° with respect to the benzene ring, and a five-membered ring having an envelope conformation. In the crystal structure, inter­molecular N—H⋯O and C—H⋯N hydrogen bonds link the mol­ecules. There is a C—H⋯π contact between the benzene ring and the methyl group of the ethyl substituent
