چکیده
The title compound, C(32)H(31)N(3)O(4), was obtained in a Suzuki coupling of carbazole diboronic acid and bromo-nitro-benzene. In the crystal, the mol-ecule adopts a non-symmetric conformation. The carbazole ring system is approximately planar [maximum deviation from the least-squares plane = 0.039 (2) Å]. The planes of the carbazole unit and the benzene rings subtend dihedral angles of 48.42 (7) and 41.81 (6)°. The dihedral angles between the planes of the nitro-phenyl rings and the nitro groups are 44.34 (19) and 61.64 (15)°. The crystal is built from two strands of parallel mol-ecules with inter-digitated octyl chains. These strands are symmetry related by a twofold screw axis.

In the crystal structure of the title compound, C(20)H(23)Br(2)N, the octyl chains are extended in an anti conformation and form a segregating bilayer, isolating rows of carbazole units. The carbazole moieties are engaged in offset π-π inter-actions; the smallest centroid-to-centroid distance is 4.2822 (11) Å. This offset packing motif allows the methyl-ene group attached directly to the N atom...

The central structural element of the title compound, C(24)H(29)NO(2), is a carbazole unit substituted with two acetyl residues and an octyl chain. The acetyl residues are nearly coplanar [dihedral angles = 5.37 (14) and 1.0 (3)°] with the carbazole unit which is essentially planar (r.m.s. deviation for all non-H atoms = 0.025 Å). The octyl chain adopts an all-trans conformation. The crystal pa...
