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.

6-(4-Methyl­phen­yl)-1,3,5-triazine-2,4-di­amine–4-methyl­benzoic acid (1/1)

The 4-methyl­benzoic acid mol­ecule of the title adduct, C₁₀H₁₁N₅·C₈H₈O₂, is approximately planar with a dihedral angle of 6.3 (2)° between the carb­oxy­lic acid group and the benzene ring. In the triazine mol­ecule, the plane of the triazine ring makes a dihedral angle of 29.2 (2)° with that of the adjacent benzene ring. In the crystal, the acid and base mol­ecules are linked via N—H...O and O—H...N hydrogen bonds with an R₂²(8) motif, and the acid–base pairs are further connected via N—H...N hydrogen bonds with R₂²(8) motifs, forming a supra­molecular ribbon along [101]. Between the tapes, a weak C—H...π inter­action is observed.
