title: cis-6-Bromo-4-(1-methyl-1H-indol-3-yl)-10,10a-dihydro-1H,4H-2,9-dioxa-3-aza-benz[f]azulene.
abstract: In the title compound, C(20)H(17)BrN(2)O(2), the seven-membered oxepine ring adopts a chair conformation. The indole moiety is essentially planar with a maximum deviation of 0.031 (3)Å. The indole ring system forms a dihedral angle of 21.87 (8)° with the mean plane of the 10-membered heterobicycle. The crystal packing is stabilized by inter-molecular C-H⋯O and C-H⋯π inter-actions.
