N-[(2,6-Di­ethyl­phen­yl)carbamo­thio­yl]-2,2-di­phenyl­acetamide

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...π and π–π [centroid–centroid seperation = 3.8821 (10) Å] inter­actions also occur in the crystal structure.
