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

The molecule of the title compound, C(22)H(28)N(2)O(2), lies across an inversion centre with one half-mol­ecule in the asymmetric unit. The mol­ecule adopts an E configuration 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 the a axis.
