Description
Summary:The title compound, C(15)H(15)NO(3), contains a carbazole skeleton with an ethoxy-carbonyl group at the 3 position. In the indole ring system, the benzene and pyrrole rings are nearly coplanar, forming a dihedral angle of 1.95 (8)°. The cyclo-hexenone ring has an envelope conformation. In the crystal structure, pairs of strong N-H⋯O hydrogen bonds link the mol-ecules into centrosymmetric dimers with R(2) (2)(10) ring motifs. π-π contacts between parallel pyrrole rings [centroid-centroid distance = 3.776 (2) Å] may further stabilize the structure. A weak C-H⋯π inter-action is also observed.
