Crystal Structure of N-Benzlidene-N′-(2-carboxyphenyl)hydrazine

Abstract

Molecules of the title compound (alternative name, benzaldehyde-2-carboxyphenylhydrazone), C₁₄H₁₂N₂O₂ adopt an E configuration about the azomethine C=N double bond. The molecule is almost planar and the dihedral angle between the planes of phenyl and carboxy phenyl rings are only 4.9(1)°. The crystal structure is stabilized by the two intermolecular O2-H…O1 hydrogen bonds between O atoms and the π-π interactions between the phenyl rings.
