چکیده
In the title compound, C(13)H(13)N(3)O, the phenyl and pyrrole rings are inclined at 47.45 (8)°. In the crystal, inter-molecular N-H⋯O and C-H⋯O hydrogen bonds form R(2) (1)(6) ring motifs. Mol-ecules connected through these hydrogen bonds are arranged into polymeric chains extending along the c axis.

In the title compound, C(9)H(7)N(3), the N-bound methyl group and vinyl H atom are syn. The 12 non-H atoms comprising the mol-ecule are essentially coplanar (r.m.s. deviation = 0.071 Å). Supra-molecular tapes feature in the crystal packing, orientated perpendicular to [10-1], and are formed by C-H⋯N inter-actions involving each cyano N atom. The tapes are connected into layers via π-π inter-act...

In the title compound, C(22)H(18)N(4)O(2)S, the seven-membered ring generated by an intra-molecular N-H⋯O hydrogen bond adopts an envelope conformation in both of the two independent mol-ecules in the asymmetric unit. In the crystal, mol-ecules are linked into C(9) chains along [100] by N-H⋯O hydrogen bonds. The mol-ecules are also weakly linked by C-H⋯O and C-H⋯N inter-actions, forming dimers ...
