In the title compound, C25H26N2OS, the diethyl-substituted benzene ring forms dihedral angles of 67.38 (9) and 55.32 (9)° with the terminal benzene rings. The mol-ecule adopts a trans-cis conformation with respect to the orientations of the di-phenyl-methane and 1,3-di-ethyl-benzene groups with respect to the S atom across the C-N bonds. This conformation is stabilized by an intra-molecular N-H⋯O hydrogen bond, which generates an S(6) ring. In the crystal, pairs of N-H⋯S hydrogen bonds link the mol-ecules into inversion dimers, forming R 2 (2)(6) loops. The dimer linkage is reinforced by a pair of C-H⋯S hydrogen bonds, which generate R 2 (2)(8) loops. Weak C-H⋯π and π-π [centroid-centroid seperation = 3.8821 (10) Å] inter-actions also occur in the crystal structure.
在标题化合物C₂₅H₂₆N₂OS中，二乙基亚苯基环与末端苯环形成的二面角分别为67.38 (9)°和55.32 (9)°。就二苯基甲烷和1,3 - 二乙苯基团相对于硫原子跨越碳 - 氮键的取向而言，该分子呈反式 - 顺式构象。这种构象通过分子内N - H⋯O氢键得以稳定，该氢键形成了一个S(6)环。在晶体中，成对的N - H⋯S氢键将分子连接成反演二聚体，形成R₂²(6)环。二聚体连接通过一对C - H⋯S氢键得到加强，这对氢键形成了R₂²(8)环。晶体结构中还存在弱的C - H⋯π和π - π[质心 - 质心间距 = 3.8821 (10) Å]相互作用。
