In the title compound, C19H19BrO2, the cyclo-hexenone ring adopts an envelope conformation with the C atom bearing the methyl substituents as the flap. In the crystal, weak π-π stacking is observed between parallel aromatic rings of adjacent mol-ecules, the centroid-centroid distance being 3.694 (6) Å. The entire bromonaphthylmethyl unit is disordered over two orientations, with a site-occupancy ratio of 0.5214 (19):0.4786 (19).
在标题化合物C₁₉H₁₉BrO₂中,环己烯酮环呈信封式构象,带有甲基取代基的C原子作为折边。在晶体中,观察到相邻分子的平行芳香环之间存在弱π-π堆积,质心间距为3.694(6) Å。整个溴萘基甲基单元在两个取向上无序,占有率之比为0.5214(19):0.4786(19)。
