Ethyl (Z)-2-cyano-3-(9-ethyl-9H-carbazol-3-yl)prop-2-enoate
In the title compound, C(20)H(18)N(2)O(2), weak inter-molecular C-H⋯O and C-H⋯N inter-actions generate a chain that runs parallel to the b axis and incorporates C(7) and R(2) (2)(15) graph-set motifs. The supra-molecular aggregation is completed by the presence of weak C-H⋯π inter-actions.

The C=C bond in the title compound, C(14)H(15)NO(4), is in an E configuration. With the exception of the methyl C atoms, the non-H atoms of the mol-ecule all lie approximately on a plane (r.m.s. deviation = 0.096 Å). π-π stacking is observed between parallel benzene rings of adjacent mol-ecules, the centroid-centroid distance being 3.7924 (8) Å.

The title compound, C(21)H(17)N(3)O(2), crystallizes with two mol-ecules in the asymmetric unit. The carbazole groups show relatively small deviations from planarity [maximum displacements from the mean carbazole plane are 0.077 (7) and 0.101 (7) Å]. The dihedral angles between the 3-nitro-benzyl-idene-amine and carbazole groups are 37.9 (1) and 37.0 (1)° in the two mol-ecules.

In the title compound, C(22)H(19)NO, the dihedral angle between the benzene ring and the carbazole ring system 77.1 (1)°.. The crystal structure is stabilized by inter-molecular aromatic π-π inter-actions between the benzene ring and the pyrrole ring of the carbazole system of neighbouring mol-ecules [centroid-centroid distance = 3.617 (4) Å]. In addition, the crystal structure exhibits a weak ...
