The title compound, C(22)H(20)N(2)O(4)·2CHCl(3), a new Schiff base compound, lies across a crystallographic inversion centre. An intra-molecular O-H⋯N hydrogen bond generates a six-membered ring, producing an S(6) ring motif. Inter-molecular bifurcated C-H⋯O hydrogen bonds involving the two O atoms of the Schiff base ligand and the H atom of the chloro-form solvent of crystallization, generate an R(2) (1)(5) ring motif. The crystal structure is stabilized by inter-molecular C-H⋯π and π-π inter-actions [centroid to centroid distance = 3.6158 (10) Å]. In the crystal structure, mol-ecules are stacked down the c axis.
标题化合物C(22)H(20)N(2)O(4)·2CHCl(3)，一种新的席夫碱化合物，位于一个晶体学反演中心上。分子内O-H⋯N氢键形成一个六元环，产生一个S(6)环模式。涉及席夫碱配体的两个O原子和结晶氯仿溶剂的H原子的分子间分叉C-H⋯O氢键，产生一个R(2)(1)(5)环模式。晶体结构通过分子间C-H⋯π和π-π相互作用[质心到质心距离 = 3.6158 (10) Å]得以稳定。在晶体结构中，分子沿c轴堆积。
