(Z)-6-[(5-Chloro-2-hydroxyphenyl)aminomethylene]-2-ethoxycyclohexa-2,4-dienone

Abstract

The title compound, C15H14ClNO3, exists as the keto-amine form in the crystal and two intramolecular N-H center dot center dot center dot O hydrogen bonds are observed. The aromatic rings are oriented at a dihedral angle of 5.85 (8)degrees. In the crystal structure, intermolecular O-H center dot center dot center dot O and C-H center dot center dot center dot O hydrogen bonds link the molecules into chains. A pi-pi contact between the benzene rings [centroid-centroid distance = 3.6623 (10) angstrom] further stabilizes the structure.
