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.
标题化合物C(22)H(28)N(2)O(2)的分子位于一个对称中心上，不对称单元中含有半个分子。该分子相对于偶氮甲碱C=N键呈E构型，且亚氨基与芳环共面。在分子内部，平面单元相互平行，但从六亚甲基桥向相反方向延伸。羟基与肟氮原子之间存在分子内O-H⋯N氢键。还存在弱的分子间C-H⋯O键，将每个分子与另外两个分子相连，沿a轴形成链状结构。
