چکیده
In the title compound, C(16)H(14)N(2)O(2), the conformation about the C=C bond is E, and the two amide groups are effectively orthogonal [the C-N-N-C torsion angle is 104.5 (2)°]. In the crystal structure, the amide groups groups associate via N-H⋯O hydrogen bonding, forming supra-molecular tapes with undulating topology along the c-axis direction.

The title compound, C(11)H(13)N(3)S, is close to being planar, with a dihedral angle of 9.64 (3)° between the benzene ring and the thio-semicarbazone mean plane, maintained by the presence of π-conjugation in the chain linking the the two systems. In the crystal, N-H⋯S hydrogen bonds form centrosymmetric dimers through a cyclic association [graph-set R(2) (2)(8)].

In the title compound, C(31)H(29)ClN(2)O(3), the two heterocyclic rings, belonging to a system of five condensed rings, adopt conformations intermediate between twist-boat and sofa. The secondary amide group is involved in a weak intramolecular N-H⋯N hydrogen bond. In the crystal, molecules are linked by pairs of C-H⋯Cl hydrogen bonds to form inversion dimers. These dimers are linked via a C-H⋯...
