The mol-ecule of the title Schiff base compound, C(28)H(32)N(2)O(2), has a twisted geometry, the dihedral angles between the central benzene ring and the other two benzene rings being 29.12 (14) and 26.01 (14)°. Four intra-molecular C-H⋯O hydrogen bonds and two intra-molecular O-H⋯N hydrogen bonds stabilize the mol-ecular structure. In the crystal packing, mol-ecules are stacked along the a axis and stabilized by π-π inter-actions [centroid-centroid distance = 3.6724 (17) Å]. The crystal studied was found to be a non-merohedral twin, the refined ratio of twin components being 0.374 (5):0.626 (5).
标题席夫碱化合物C(28)H(32)N(2)O(2)的分子具有扭曲的几何形状，中心苯环与另外两个苯环之间的二面角分别为29.12 (14)°和26.01 (14)°。四个分子内C—H⋯O氢键和两个分子内O—H⋯N氢键稳定了分子结构。在晶体堆积中，分子沿a轴堆积，并通过π-π相互作用[质心-质心距离 = 3.6724 (17) Å]得以稳定。研究发现所研究的晶体为非等轴孪晶，孪晶组分的精修比例为0.374 (5):0.626 (5)。
