The title compound, C15H13NO2, crystallizes with two mol­ecules (A and B) in the asymmetric unit. The carbazole ring systems of both mol­ecules are close to planar (r.m.s deviations = 0.035 and 0.053 Å). In the crystal, A+A and B+B inversion dimers linked by pairs of O—H⋯O hydrogen bonds generate R22(8) loops and weak C—H⋯π inter­actions link the dimers into a three-dimensional network.

Structure description

Compounds based on carbazole ring systems have been reported to exhibit diverse biological activities such as cytotoxic, anti­tumor, anti­viral, anti­microbial, anti­parasitics, anti­serotonin and anti-inflammatory activities (e.g.: Kumara Swamy et al., 2009[Kumara Swamy, K. C., Bhuvan Kumar, N. N., Balaraman, E. & Pavan Kumar, K. V. P. (2009). Chem. Rev. 109, 2551-2651.]; Broadbent et al., 1998[Broadbent, A., Thomas, H. & Broadbent, S. (1998). Curr. Med. Chem. 5, 469-491.]; Xia et al., 2008[Xia, Y., Fan, C.-D., Zhao, B.-X., Zhao, J., Shin, D.-S. & Miao, J.-Y. (2008). Eur. J. Med. Chem. 43, 2347-2353.]). As part of our studies in this area, we herein report the synthesis and crystal structure of the title compound.

As shown in Fig. 1[link], there are two mol­ecules (A and B) in the asymmetric unit: the carbazole ring systems of both mol­ecules are close to planar (r.m.s deviation = 0.035 and 0.053 Å). The bond-length distributions within the mol­ecules A and B of the title compound are almost identical. These values are in good agreement with those observed in related structures (Akkurt et al., 2015[Akkurt, M., Jasinski, J. P., Mohamed, S. K., El-Emary, T. I. & Albayati, M. R. (2015). Acta Cryst. E71, o937-o938.]; Fun et al., 2010[Fun, H.-K., Goh, J. H., Asiri, A. M., Khan, S. A. & Khan, K. A. (2010). Acta Cryst. E66, o1200-o1201.]; Archana et al., 2010[Archana, R., Prabakaran, K., Rajendra Prasad, K. J., Thiruvalluvar, A. & Butcher, R. J. (2010). Acta Cryst. E66, o3146.]).

In the crystal, pairwise O—H⋯O hydrogen bonds link pairs of mol­ecules into A+A and B+B inversion dimers with R22(8) ring motifs (Fig. 2[link], Table 1[link]). The three-dimensional architecture is consolidated by C—H⋯π inter­actions (Table 1[link]).

Synthesis and crystallization

The title compound was obtained as an unexpected product of the reaction of 9,9a-di­hydro-4aH-carbazole (0.01 mol, 1.69 g) with an excess of ethyl 3-chloro­propano­ate (0.1 mol, 13.7 g) in the presence of potassium carbonate under reflux for 3 h. The intended product was the corresponding ethyl ester, {ethyl 3-[4aH-carbazol-9(9aH)-yl]propano­ate}. We assume that the ester has been hydrolysed under the basic reaction conditions employed into the corresponding carb­oxy­lic acid (title compound). The title compound was isolated by plate-layer chromatography (PLC) then the extracted product was dissolved in di­methyl­sulfoxide and left to evaporate slowly at room temperature to give colourless plates. The purity of the product was confirmed by TLC using ethyl acetate:cyclo­hexane (10: 1) as the mobile phase.

Special details top

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