The mol-ecule of the title compound, C(21)H(26)N(2)O(6), which lies across a crystallographic inversion centre, crystallizes with two unique half-molecules in the symmetric unit and adopts a linear configuration and the imino group is coplanar with the aromatic ring, making a dihedral angle of 3.26 (3)°. Strong intra-molecular O-H⋯N and weak inter-molecular O-H⋯O and C-H⋯O hydrogen bonds and weak inter-molecular π-π stacking inter-actions [centroid-centroid distance = 4.419 (2) Å]establish an infinite three-dimensional supra-molecular structure.
标题化合物C(21)H(26)N(2)O(6)的分子跨越一个晶体学反演中心，在对称单元中以两个独特的半分子形式结晶，呈线性构型，亚氨基与芳环共面，二面角为3.26 (3)°。强分子内O-H⋯N和弱分子间O-H⋯O及C-H⋯O氢键以及弱分子间π-π堆积相互作用[质心-质心距离 = 4.419 (2) Å]形成了一个无限的三维超分子结构。
