(E)-5-[(3-chlorophenyl)diazenyl]-2-hydroxy-3-methoxybenzaldehyde

Abstract

The title compound, C14H11ClN2O3, contains an azo group (-N=N-), and the configuration around the -N=N- double bond is trans. There are intramolecular O-H (...) O and intermolecular C-H (...) O hydrogen bonds, and the crystal packing is stabilized by C-H (...)pi and pi-pi stacking interactions, forming a two-dimensional network.
