چکیده
In the title compound, C(19)H(15)BrO(3), the dihedral angle between the naphthalene ring system and the benzene ring is 72.02 (9)°. The bridging carbonyl C-C(=O)-C plane makes dihedral angles of 70.88 (10) and 1.87 (12)°, respectively, with the naphthalene ring system and the benzene ring. In the crystal, two types of weak inter-molecular C-H⋯O inter-actions and a short Br⋯C contact [3.345 (2) Å] are observed.
