The asymmetric unit of the title compound, C44H44N2O6, contains two independent mol-ecules with similar conformations. The di-hydro-naphthalene ring systems are approximately planar [maximum deviations = 0.036 (2), 0.128 (2), 0.0.24 (2) and 0.075 (2) Å]. The dihedral angle between two di-hydro-naphthalene ring systems is 83.37 (4)° in one mol-ecule and 88.99 (4)° in the other. The carbonyl O atom is linked with the adjacent hy-droxy and imino groups via intra-molecular O-H⋯O and N-H⋯O hydrogen bonds. In the crystal, mol-ecules are linked through O-H⋯O hydrogen bonds into layers parallel to (001), and adjacent layers are further stacked by π-π inter-actions between di-hydro-naphthalene and phenyl rings into a three-dimensional supra-molecular architecture. In the crystal, one of the isopropyl groups is disordered over two positions with an occupancy ratio of 0.684 (8):0.316 (8).
标题化合物C44H44N2O6的不对称单元包含两个构象相似的独立分子。二氢萘环系近似平面 [最大偏差 = 0.036 (2)、0.128 (2)、0.0.24 (2) 和0.075 (2) Å]。两个二氢萘环系之间的二面角在一个分子中为83.37 (4)°，在另一个分子中为88.99 (4)°。羰基O原子通过分子内O-H⋯O和N-H⋯O氢键与相邻的羟基和亚氨基相连。在晶体中，分子通过O-H⋯O氢键连接成平行于(001)的层，相邻层通过二氢萘环与苯环之间的π-π相互作用进一步堆积成三维超分子结构。在晶体中，其中一个异丙基在两个位置上无序，占有率为0.684 (8):0.316 (8)。
