Ethyl 1-oxo-1,2,3,4-tetra-hydro-9H-carbazole-3-carboxyl-ate.

ABSTRACT: 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. ?-? contacts between parallel pyrrole rings [centroid-centroid distance = 3.776?(2)?Å] may further stabilize the structure. A weak C-H?? inter-action is also observed.
