Abstract

In the title compound, C(15)H(15)NO(3), the carbazole skeleton includes an eth-oxy-carbonyl group at the 3-position. In the indole ring system, the benzene and pyrrole rings are nearly coplanar, forming a dihedral angle of 0.89 (4)°. The cyclo-hexenone ring has an envelope conformation. In the crystal, inter-molecular N-H⋯O and C-H⋯O hydrogen bonds link the mol-ecules into a three dimensional network. A weak C-H⋯π inter-action is also observed.

摘要

在标题化合物C₁₅H₁₅NO₃中，咔唑骨架在3位包含一个乙氧羰基。在吲哚环系中，苯环和吡咯环近乎共面，形成的二面角为0.89 (4)°。环己烯酮环具有信封式构象。在晶体中，分子间的N-H⋯O和C-H⋯O氢键将分子连接成三维网络。还观察到一个弱的C-H⋯π相互作用。
