2,2′-[1,1′-(Hexane-1,6-diyldioxydinitrilo)diethylidyne]diphenol

Abstract

The molecule of the title compound, C22H28N2O2, lies across an inversion centre with one half-molecule in the asymmetric unit. The molecule adopts anEconfiguration with respect to the azomethine C=N bond and the imino group is coplanar with the aromatic ring. Within the molecule, the planar units are parallel, but extend in opposite directions from the hexamethylene bridge. There are intramolecular O—H...N hydrogen bonds between the hydroxyl groups and the oxime N atoms. There are also weak intermolecular C—H...O bonds that link each molecule to two others, forming chains along theaaxis.
