9-Ethyl-9H-carbazole-3-carbaldehyde
The title mol-ecule, C(15)H(13)NO, approximates a planar conformation except for the alkyl chain (ethyl group) bonded to the N atom with a maximum deviation from the least-squares plane through the 15 planar atoms of 0.120 (2) Å for the O atom. The distance of the formyl O atom from the plane of the carbazole ring is 0.227 (2) Å. The N-C bond lengths in the central ring are significantly differ...
متن کاملEthyl 4,9-dimethyl-9H-carbazole-3-carboxylate
In the title compound, C17H17NO2, the carbazole skeleton includes an eth-oxy-carbonyl group at the 3-position. The indole three-ring system is almost planar [maximum deviation = 0.065 (2) Å], and the ethyl ester group is inclined to its mean plane by 15.48 (2)°. In the crystal, there are π-π stacking inter-actions between parallel benzene rings and between parallel benzene and pyrrole rings of ...

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 ...
متن کامل9-Ethyl-N-(3-nitrobenzylidene)-9H-carbazol-3-amine
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.
متن کاملEthyl 2-(3-chloro-2-pyridyl)-5-oxopyrazolidine-3-carboxylate
In the mol-ecule of the title compound, C(11)H(12)ClN(3)O(3), the five membered ring adopts an envelope conformation. In the crystal structure, inter-molecular N-H⋯O hydrogen bonds link the mol-ecules into centrosymmetric dimers.
