3-(3-Bromo-benz-yl)-1H-isochromen-1-one.

In the title compound, C(16)H(11)BrO(2), the isocoumarin ring system is planar (r.m.s. deviation = 0.015†à ) and subtends a dihedral angle of 88.90†(2)° with the bromo-benzene ring. In the crystal, mol-ecules are linked, forming a three-dimensional packing pattern involving C-H⋯O inter-actions, Br⋯O contacts [3.4734†(10)†à ] and π-π stacking inter-actions with centroid-centroid distances ranging from 3.667†(2) to 3.765†(2)†à .
