In the title mol-ecule, C23H22N2OS, the di-phenyl-acetyl and ethyl-benzene groups adopt a trans-cis conformation, respectively, with respect to the S atom across the (S=)C-N bonds. This conformation is stabilized by an intra-molecular N-H⋯O hydrogen bond and a weak C-H⋯S hydrogen bond. The ethyl-substituted benzene ring forms dihedral angles of 87.53 (15) and 73.94 (15)° with the phenyl rings. In the crystal, N-H⋯O hydrogen bonds link mol-ecules into chains along [100]. A weak C-H⋯π inter-action is also observed.
在标题分子C₂₃H₂₂N₂OS中，二苯乙酰基和乙苯基团相对于硫原子分别通过（S=）C-N键采取反式-顺式构象。这种构象通过分子内N-H⋯O氢键和弱C-H⋯S氢键得以稳定。乙基取代的苯环与苯环形成的二面角分别为87.53 (15)°和73.94 (15)°。在晶体中，N-H⋯O氢键将分子沿[100]方向连接成链。还观察到一种弱的C-H⋯π相互作用。
