title: (E,E)-2,2'-[1,1'-(Cyclohexane-1,2-diyl-dinitrilo)diethylidyne]diphenol.
abstract: The title compound, C(22)H(26)N(2)O(2), is chiral; the absolute configuration follows from the known chirality of the input reagents. The asymmetric unit contains two crystallographically independent mol-ecules in different orientations. The two mol-ecules are related to each other by a non-crystallographic twofold rotation axis, while each mol-ecule exhibits a further pseudo-twofold axis. Bond distances and angles are similar in the two mol-ecules. Inter-molecular C-H⋯π(ring) inter-actions and intra-molecular O-H⋯N hydrogen bonds are observed in the crystal structure.
