Polymorph of 4-(carbazol-9-yl)benzonitrile
The asymmetric unit of the title compound, C(19)H(12)N(2), contains two independent mol-ecules with a similar structure. In the two mol-ecules, the dihedral angles between the carbazole ring system and the benzene ring are 47.9 (5) and 45.4 (4)°, similar to the value of 47.89 (6)° found in the previously reported structure [Saha & Samanta (1999 ▶). Acta Cryst. C55, 1299-1300]. In the crystal, t...

In the title compound, C(21)H(18)N(2)O, the dihedral angle between the phenol ring and the carbazole system is 39.34 (2)°. Inter-molecular O-H⋯N hydrogen bonds and C-H⋯π and π-π inter-actions [centroid-centroid distances = 3.426 (2) and 3.768 (2) Å] stabilize the crystal structure.

In the title compound, C(28)H(30)N(2)O(2), the cyclo-hexene ring system adopts a sofa conformation. The crystal structure is stabilized by C-H⋯O inter-actions between methyl H atoms of the ethyl substituents and the O atoms of carbonyl groups of adjacent mol-ecules, and by an inter-molecular carbon-yl-carbonyl inter-actions [3.207 (2) Å].
متن کامل2-[4-(Carbazol-9-yl)phenyl]-1,3-diethyl-1,3-diphenylguanidine
In the title compound, C35H32N4, the C-N bond lengths in the guanidine part are 1.286 (3), 1.387 (2) and 1.414 (2) Å, indicating double- and single-bond character. The N-C-N angles are 114.48 (17), 118.78 (17) and 126.72 (17)°, showing a deviation of the CN3 plane from an ideal trigonal-planar geometry. The carbazole ring system is almost planar (r.m.s. deviation = 0.002 Å). In the crystal, mol...
