In the title compound, C15H15NO, the dihedral angle between the benzene rings is 2.25 (2)°. The C—C—C—O atoms of the propanol side chain are in a gauche conformation [torsion angle = −60.5 (2)°]. In the crystal, O—H⋯O hydrogen bonds link the molecules into C(2) chains propagating in [100]. The O-bonded H atom is disordered over two sites of equal occupancy.

Carbazole (5 g, 0.03 moles), sodium hydride (2.88 g, 0.12 moles) and dry THF (400 ml) were placed in a 3-neck round bottomed flask equipped with a magnetic stirrer. The flask was purged with dry N2 gas, sealed and placed in a salt ice-bath (-15 °C). The reaction mixture was allowed to stir for 1 h. 3-bromo-1-propanol (4 g, 0.03 mole), was then added slowly to the reaction mixture through a syringe. The reaction was allowed to continue for a period of 12 h, at ambient temperature. The product obtained was isolated by quenching the excess sodium hydride and the solvent was evaporated. The final product was dissolved in ethyl acetate, rinsed with water and dried with anhydrous MgSO4. The product was purified by
technique using 10% ethyl acetate in hexane as the to obtain pure bright white crystals. Recrystallization of the compound from chloroform gave colourless blocks of (I).The oxygen H atom was located in a diference Fourier map and refined isotropically. Other hydrogen atoms were fixed geometrically and allowed to ride on the parent carbon atoms, with aromatic C—H = 0.93 Å and methylene C—H = 0.97 Å. The displacement parameters were set for phenyl H atoms at Uiso(H) = 1.2Ueq(C)and methylene H atoms at Uiso (H) = 1.2Ueq(C). The oxygen H atom is disordered in two orientations.
The title compound, C15H15NO, (I) is a carbazole based alcohol derivative. It has a tricyclic structure, consisting of two six-membered benzene ring fused on either side of a five-membered nitrogen-containing ring (Uludağ et al. 2010; Chen et al. 2009). A propan-1-ol group is linked to the nitrogen atom of the carbazole.
It is an important heterocyclic aromatic compound in which the alcohol group is used as a linker for the preparation of various carbazole derivatives (Murugavel et al. 2009; Chakkaravarthi et al. 2008). The tricyclic structure is essentially planar, making a dihedral angle of 2.25 (2)° with the two outer most aromatic rings. The crystal packing is stabilized by a bifurcated O—H···O interaction linking the molecules into chains along the a axis.

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. |
Refinement. Refinement of F2 against ALL reflections. The weighted R-factor wR and goodness of fit S are based on F2, conventional R-factors R are based on F, with F set to zero for negative F2. The threshold expression of F2 > σ(F2) is used only for calculating R-factors(gt) etc. and is not relevant to the choice of reflections for refinement. R-factors based on F2 are statistically about twice as large as those based on F, and R- factors based on ALL data will be even larger. |

The title compound, C15H15NO, (I) is a carbazole based alcohol derivative. It has a tricyclic structure, consisting of two six-membered benzene ring fused on either side of a five-membered nitrogen-containing ring (Uludağ et al. 2010; Chen et al. 2009). A propan-1-ol group is linked to the nitrogen atom of the carbazole.
It is an important heterocyclic aromatic compound in which the alcohol group is used as a linker for the preparation of various carbazole derivatives (Murugavel et al. 2009; Chakkaravarthi et al. 2008). The tricyclic structure is essentially planar, making a dihedral angle of 2.25 (2)° with the two outer most aromatic rings. The crystal packing is stabilized by a bifurcated O—H···O interaction linking the molecules into chains along the a axis.
