In the title compound, C20H14N2, the carbazole ring system is essentially planar (r.m.s. deviation = 0.187 Å) and is inclined at an angle of 54.33 (4) ° with respect to the benzene ring. The crystal packing is stabilized by weak C—H⋯N and C—H⋯π interactions.

To a stirred solution of AlCl3 (2.8 g, 2.1 mmol), in dry THF (100 ml) sodium azide (4.1 g, 6.31 mmol), and 9-p-tolyl-9H-carbazole-3-carbaldehyde (3 g, 1.05 mmol) were added and the resulting mixture was heated to gentle reflux. The progress of the reaction was monitored by TLC. The suspension gradually turned pale yellow after 5–6 h. Then excess THF was removed by distillation and the residue was diluted with 10% HCl (10 ml). The aqueous layer was extracted with CHCl3 (2x50 ml) and brine (25 ml). The organic layer was separated and dried over anhydrous sodium sulfate. The solvent was distilled off under reduced pressure and the residue was purified by
by elution with mixture of ethyl acetate and hexane (1:4) to give the title compound as colorless crystalline solid.(m.p 449 K).The H atoms were positioned geometrically and refined using riding model with C—H = 0.93 and 0.96Å for aryl and methyl type H-atoms, respectively, and Uiso(H) = 1.2 or 1.5 times Ueq(C) for aromatic or methyl H-atoms.
Carbazole derivatives possess antioxidative (Tachibana et al., 2001), antitumor (Itoigawa et al., 2000), anti-inflammatory and antimutagenic (Ramsewak et al., 1999) activities.
The geometric parameters of the title molecule (Fig. 1) agree well with the corresponding geometric parameters reported in similar structures (Archana et al., 2010; Velmurugan et al., 2010; Yuan et al., 2010). The carbazole ring system is essentially planar with maximum deviation of C9 from the least-squae plane defined by the atoms N1/C1–C12 being 0.0306 (10) Å. The mean plane of the carbazole ring system makes a dihedral angle of 54.33 (4) ° with the phenyl ring. The sum of bond angles around N1 [359.87 (10) °]indicates the sp2 π interactions involving the centroid of C1–C6 ring (Table 1).

The crystal packing of the compound is stabilized by weak C8—H8···N2 hydrogen bonds and C15—H15···For the biological activity of carbazole derivatives, see: Ramsewak et al. (1999); Tachibana et al.

Geometry. All e.s.d.'s (except the e.s.d. in the dihedral angle between two l.s. planes) are estimated using the full covariance matrix. The cell e.s.d.'s are taken into account individually in the estimation of e.s.d.'s in distances, angles and torsion angles; correlations between e.s.d.'s in cell parameters are only used when they are defined by crystal symmetry. An approximate (isotropic) treatment of cell e.s.d.'s is used for estimating e.s.d.'s involving l.s. planes. |

Carbazole derivatives possess antioxidative (Tachibana et al., 2001), antitumor (Itoigawa et al., 2000), anti-inflammatory and antimutagenic (Ramsewak et al., 1999) activities.
The geometric parameters of the title molecule (Fig. 1) agree well with the corresponding geometric parameters reported in similar structures (Archana et al., 2010; Velmurugan et al., 2010; Yuan et al., 2010). The carbazole ring system is essentially planar with maximum deviation of C9 from the least-squae plane defined by the atoms N1/C1–C12 being 0.0306 (10) Å. The mean plane of the carbazole ring system makes a dihedral angle of 54.33 (4) ° with the phenyl ring. The sum of bond angles around N1 [359.87 (10) °]indicates the sp2 hybridization state of atom N1 in the molecule. The crystal packing of the compound is stabilized by weak C8—H8···N2 hydrogen bonds and C15—H15···π interactions involving the centroid of C1–C6 ring (Table 1).
