(9H-Carbazol-9-ylmethyl)diethylamine

The asymmetric unit of the title compound, C(17)H(20)N(2), contains two mol-ecules, whose bond lengths and angles differ only slightly. In the crystal, neighbouring mol-ecules form pillar structures via edge-to-face π-π stacking inter-actions [edge-to-face distances = 3.538 (3) and 3.496 (3)Å].

2-(Carbazol-9-yl)acetic acid

In the title compound, C(14)H(11)NO(2), the tricyclic aromatic ring system is essentially planar [maximum deviation = 0.025 (2) Å]. The dihedral angle between the two benzene rings is 2.8 (5)°, while the carboxyl group forms a dihedral angle of 88.5 (1)° with the pyrrole ring. Inter-molecular O-H⋯O hydrogen bonds may contribute to the overall stabilization of the crystal structure.

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...

9-[3-(Carbazol-9-yl)-5-methylphenyl]carbazole

The title compound, C31H22N2, crystallizes with two symmetry-independent mol-ecules in the asymmetric unit. The mol-ecules have slightly different conformations, the dihedral angles between the central phenyl ring and the carbazolyl groups being 56.29 (4) and 59.57 (4)° in one mol-ecule and 48.71 (4) and 65.47 (4)° in the other. In the crystal, mol-ecules are linked by weak C-H⋯π and π-π [centr...
