当从标题化合物C20 H26 N2 O3 S的中心S → N轴向下观察时，很明显，分子采用了一种扭曲构象，所有的O原子位于中心苯环的一侧;羰基O原子远离中心环，N-键合的乙基位于分子的一侧。超分子螺旋链沿着B轴排列，并由C-H-O接触维持。这些通过C-H π相互作用在三维结构中被巩固。
When viewed down the central S⋯N axis of the title compound, C20H26N2O3S, it is apparent that the molecule adopts a gauche conformation with all O atoms lying to one side of the central benzene ring; the carbonyl O atom is directed away from the central ring and the N-bound ethyl groups lie to one side of the molecule. Supramolecular helical chains aligned along the b axis and sustained by C—H⋯O contacts feature in the crystal packing. These are consolidated in the three-dimensional structure by C—H⋯π interactions.
