Abstract
The title compound, C15H13NO2, crystallizes with two molecules (AandB) 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+AandB+Binversion dimers linked by pairs of O—H...O hydrogen bonds generateR22(8) loops and weak C—H...π interactions link the dimers into a three-dimensional network.

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; Broadbent et al, 1998; Xia et al, 2008)
Summary
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; Broadbent et al, 1998; Xia et al, 2008). As part of our studies in this area, we report the synthesis and crystal structure of the title compound. 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 A ). 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; Fun et al, 2010; Archana et al, 2010). Pairwise O—HÁ Á ÁO hydrogen bonds link pairs of molecules into A+A and B+B inversion dimers with R22(8) ring motifs (Fig. 2, Table 1).
