Abstract: 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 mol­ecule adopts a trans-cis conformation with respect to the orientations of the di­phenyl­methane and 1,3-di­ethyl­benzene groups with respect to the S atom across the C-N bonds. This conformation is stabilized by an intra­molecular N-H...O hydrogen bond, which generates an S(6) ring. In the crystal, pairs of N-H...S hydrogen bonds link the mol­ecules into inversion dimers, forming R22(6) loops. The dimer linkage is reinforced by a pair of C-H...S hydrogen bonds, which generate R22(8) loops. Weak C-H...[pi] and [pi]-[pi] [centroid-centroid seperation = 3.8821 (10) Å] inter­actions also occur in the crystal structure.
