2-{[2-(2-Hydroxy-5-methoxybenzylidene)hydrazin-1-ylidene]methyl} -4-methoxyphenol

Abstract

The title phenylhydrazine derivative, C16H16N2O4, has a crystallographically imposed centre of symmetry. Except for the methyl group, all non-H atoms are almost coplanar (r.m.s. deviation = 0.0095Å). Intramolecular O - HN hydrogen bonds are observed, generating S(6) graph-set ring motifs. © Taha et al. 2014.
