In the indole ring system, the benzene and pyrrole rings are nearly coplanar, forming a dihedral angle of 1.95 (8)degrees. The cyclohexenone ring has an envelope conformation. In the crystal structure, pairs of strong N-H center dot center dot center dot O hydrogen bonds link the molecules into centrosymmetric dimers with R-2(2)(10) ring motifs. pi-pi contacts between parallel pyrrole rings [centroid-centroid distance = 3.776 (2)angstrom] may further stabilize the structure. A weak C-H center dot center dot center dot O interaction is also observed.eninfo:eu-repo/semantics/openAccessArticle10.1107/S160053680902385X2-s2.0-67650844966U350921582955Q3170265WOS:000267385300313Q4
