9-Ethyl-3-(9H-9-ethylcarbazol-3-yl)-4-nitro-9H-carbazole

Abstract

In the molecule of the title compound, C28H23N3O2, the nitro group is almost perpendicular to the carbazole ring to which it is attached. The crystal packing is determined by C-H center dot center dot center dot O and pi-pi interactions, where the nitrated carbazole ring of one molecule associates in a shifted parallel planar orientation with the centrosymmetrically related non-nitrated carbazole ring of a neighbouring molecule.
