چکیده
In the title compound, C(18)H(17)N(3)O, the dihedral angle between the phenyl and benzene rings is 11.22 (14)°. Apart from the methyl H atoms, the mol-ecule is close to planar, with a maximum deviation of 0.145 (3) Å. Intra-molecular C-H⋯O and C-H⋯N inter-actions occur. In the crystal, inversion dimers linked by pairs of N-H⋯N hydrogen bonds occur, resulting in an R(2) (2)(12) ring motif. Further C-H⋯N and C-H⋯O bonds generate R(1) (2)(7) and R(2) (2)(22) motifs and a C-H⋯π inter-action also occurs.

In the title compound, C22H19NO3S, the terminal phenyl and methyl-phenyl rings are twisted by 37.35 (12) and 49.08 (13)°, respectively, to the central benzene ring. In the crystal, mol-ecules are linked by classical N-H⋯O hydrogen bonds and weak C-H⋯O hydrogen bonds into a three-dimensional supra-molecular network.

In the title compound, C(44)H(48)N(6), the essentially planar mol-ecule [maximum deviation from the mean plane of the π system of 0.271 (3) Å] is located on a crystallographic centre of inversion. The almost planar (angle sums at N atoms = 357.6 and 357.1°) dimethyl-amino groups and short C-N bonds of the aniline groups [both 1.379 (4) Å] indicate strong electronic coupling between these groups...
