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

B. Gao

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-HN and O-HN 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-HO and C-HN hydrogen bonds link the molecules. There is a C-H contact between the benzene ring and the methyl group of the ethyl substituent.
