2,2′-{[(1E,1′E)-(Cyclo­hexane-1,4-diyl)­bis(aza­nylyl­idene)]bis­(ethan-1-yl-1-yl­idene)}diphenol

The title compound, C(22)H(26)N(2)O(2), crystallizes with three independent mol­ecules, two of which are situated on inversion centers, so the asymmetric unit contains two independent half-mol­ecules and one mol­ecule in a general position. The two hy­droxy groups in each mol­ecule are involved in intra­molecular O—H⋯N hydrogen bonds, which generate S(6) rings. In the crystal, weak inter­molecular C—H⋯π inter­actions link the mol­ecules into two crystallographically independent columns propagating along [001]; one column consists of mol­ecules in general positions, while the other column is built from alternating independent centrosymmetric mol­ecules.
