2-(1-Propyl-2,6-distyryl-1,4-dihydropyridin-4-ylidene)malononitrile
In the title compound, C(27)H(23)N(3), the dihedral angles between the central pyridine ring and the two outer benzene rings are 32.6 (1) and 52.0 (1)°. The compound displays inter-molecular π-π inter-actions between adjacent six-membered rings, the shortest centroid-centroid distance being 3.981 (3) Å.

The reaction of 2-(amino-meth-yl)pyridine and 4-toluene-sulfonyl chloride in CH(2)Cl(2) at pH 8 led to the title compound, C(20)H(20)N(2)O(4)S(2). The aromatic rings are almost perpendicular to each other and the dihedral angles between the aromatic ring planes are 74.33 (9) (central pyridine versus benzene ring of the tosyl group bonded to the imine functionality), 73.77 (6) (pyridine versus b...

In the title compound, C(17)H(19)NO(4)S, the terminal ethyl group is disordered over two sets of sites, with refined site occupancies of 0.536 (7) and 0.464 (7). The dihedral angle between the two aromatic rings is 81.92 (12)°. The mol-ecular conformation is stabilized by intra-molecular N-H⋯O and C-H⋯O hydrogen bonds, which generate S(6) motifs. In the crystal, mol-ecules are linked by C-H⋯O h...

In the title compound, C(18)H(17)N(3), the dihedral angle between the dihydropyridine and phenyl rings is 72.57 (5)° and that between the dihydropyridine ring and malononitrile plane is 5.19 (20)°. The C-C bond lengths in the pyridine ring are considerably shorter than those of normal single bonds, indicating that electrons on the dihydropyridine ring, including the non-bonding electrons of the...

The title compound, C(29)H(29)NO(3), the nearly planar nine-membered indanedione ring [maximum deviation = 0.027 (2) Å] is located approximately parallel to its carrier pyridine ring [maximum deviation = 0.021 (2) Å] with a dihedral angle of 1.8 (1)° between the planes. However, because of steric hindrance, the benzene ring [maximum deviation = 0.006 (2) Å] is not parallel to the pyridine ring ...
