In the crystal structure of the title Schiff base compound, C(18)H(20)N(2)O(4)S(2), the mol-ecule lies across a crystallographic inversion centre. The torsion angle of the N-C-C-N fragment is 180°, as the inversion centre bis-ects the central C-C bond. The crystal packing is stabilized by C-H⋯O hydrogen bonds and aromatic π-π stacking inter-actions with a centroid-centroid distance of 3.913 (2) Å.
在标题席夫碱化合物C(18)H(20)N(2)O(4)S(2)的晶体结构中，分子位于一个晶体学倒转中心上。由于倒转中心平分中心C-C键，N-C-C-N片段的扭转角为180°。晶体堆积通过C-H⋯O氢键和芳香π-π堆积相互作用得以稳定，质心-质心距离为3.913 (2) Å。
