3-(3-Bromo­benz­yl)-1H-isochromen-1-one

In the title compound, C16H11BrO2, the isocoumarin ring system is planar (r.m.s. deviation = 0.015 Å) and subtends a dihedral angle of 88.90 (2)° with the bromo­benzene ring. In the crystal, mol­ecules are linked, forming a three-dimensional packing pattern involving C—H⋯O inter­actions, Br⋯O contacts [3.4734 (10) Å] and π–π stacking inter­actions with centroid–centroid distances ranging from 3.667 (2) to 3.765 (2) Å

3-(3-Bromobenzyl)isoquinolin-1(2H)-one

In the title compound, C16H12BrNO, the ring systems subtend an interplanar dihedral angle of 75.95 (3)°. In the crystal packing, molecules are linked to form centrosymmetric pairs by pairs of classical N—H...O hydrogen bonds
