(E)-3-(9-Ethyl-9H-carbazol-3-yl)-1-(2-methoxyphenyl)prop-2-en-1-one
In the title mol-ecule, C24H21NO2, the dihedral angle between the carbazole ring system [with a maximum deviation of 0.052 (2) Å] and the benzene ring is 38.6 (1)°. In the crystal, weak bifurcated (C-H)2⋯O hydrogen bonds link the mol-ecules into chains along [100].
متن کامل(E)-3-(Anthracen-9-yl)-1-(2-bromophenyl)prop-2-en-1-one
The mol-ecule of the title chalcone, C(23)H(15)BrO, is not planar and exists in the E configuration with respect to the central C=C bond. The dihedral angle between the benzene and anthracene rings is 83.58 (6)°. The prop-2-en-1-one bridge makes dihedral angles of 63.00 (7) and 42.62 (16)° with the benzene and anthracene rings, respectively. In the crystal, mol-ecules are linked into dimers by ...
متن کامل3-(9H-Carbazol-9-yl)-2H-chromen-2-one
The title compound, C(21)H(13)NO(2), was prepared as an example of a new synthesis of carbazoles from a cyclic dibenzo-iodo-lium salt via a twofold Pd-catalysed aryl-ation of a primary amine. The two essentially planar π-subsystems [maximum deviations from the mean square plane of 0.038 (2) Å in the carbazole and 0.059 (2) Å in the coumarine unit] open a dihedral angle of 63.05 (4)°. Two mol-ec...

In the mol-ecule of the title heteroaryl chalcone derivative, C(21)H(14)O(2), the almost planar prop-2-en-1-one unit [r.m.s. deviation = 0.0087 (1) Å] forms dihedral angles of 5.81 (7) and 49.85 (6)°, respectively, with the furan ring and anthracene ring system. In the crystal structure, the mol-ecules are linked into a two-dimensional network parallel to (100) by C-H⋯O hydrogen bonds and π⋯π i...
متن کاملN-[(E)-(9-Ethyl-9H-carbazol-3-yl)methylidene]aniline
The title compound, C(21)H(18)N(2), was obtained as the product of the reaction between 9-ethyl-9H-carbazole-3-carbaldehyde and aniline in ethanol. The crystal packing is stabilized mainly by C-H⋯π inter-actions between the carbazole benzene rings and the methyl-ene H atoms.
