Abstract

In the title compound, C17H17NO2, the carbazole skeleton includes an ethoxycarbonyl group at the 3-position. The indole three-ring system is almost planar [maximum deviation = 0.065 (2) angstrom], and the ethyl ester group is inclined to its mean plane by 15.48 (2)degrees. In the crystal, there are pi-pi stacking interactions between parallel benzene rings and between parallel benzene and pyrrole rings of adjacent molecules [centroid-centroid distances = 3.9473 (8) and 3.7758 (8) angstrom, respectively]. Weak C-H center dot center dot center dot pi interactions are also present.
