(E,E)-2,2′-[1,1′-(Cyclohexane-1,2-diyldinitrilo)diethylidyne]diphenol

Abstract

The title compound, C22H26N2O2, is chiral; the absolute configuration follows from the known chirality of the input reagents. The asymmetric unit contains two crystallographically independent molecules in different orientations. The two molecules are related to each other by a non-crystallographic twofold rotation axis, while each molecule exhibits a further pseudo-twofold axis. Bond distances and angles are similar in the two molecules. Intermolecular C—H...π(ring) interactions and intramolecular O—H...N hydrogen bonds are observed in the crystal structure.
