title: 5-Bromo-2,3-dihydro-1H-cyclo-penta-[a]naphthalen-1-one.
abstract: The title compound, C(13)H(9)BrO, has been synthesized by the intra-molecular Friedel-Crafts reaction of 1-(1-bromo-4-naphth-yl)-3-chloro-propan-1-one. There are two approximately planar [maximum deviations of 0.8 (2) and 0.4 (2) Å in the two mol-ecules] molecules in the asymmetric unit. The dihedral angle between their mean planes is 19.72 (8)°. Weak inter-molecular C-H⋯O hydrogen bonding is present in the crystal structure.
