Abstract

The molecule of the title compound, C(22)H(28)N(2)O(2), lies across an inversion centre with one half-mol-ecule in the asymmetric unit. The mol-ecule adopts an E configuration with respect to the azomethine C=N bond and the imino group is coplanar with the aromatic ring. Within the mol-ecule, the planar units are parallel, but extend in opposite directions from the hexa-methyl-ene bridge. There are intra-molecular O-H⋯N hydrogen bonds between the hydroxyl groups and the oxime N atoms. There are also weak inter-molecular C-H⋯O bonds that link each mol-ecule to two others, forming chains along the a axis.
