In the title compound, C(18)H(13)BrClNO(3), the heterocyclic ring of the indole is distorted from planarity towards an envelope conformation. The orientations of the indole, oxetane, chloro and bromophenyl substituents are conditioned by the sp(3) states of the spiro-junction and the Cl-attached C atoms.
