3-Acet­yl-7-methoxy­coumarin

In the title mol­ecule, C₁₂H₁₀O₄, the lactone and benzene rings are coplanar, while the plane of the acet­yl substituent is rotated by 12.26 (9)° from the mol­ecular plane. The mol­ecules stack through π–π inter­actions along [100] and these stacks are laterally connected by C—H...O hydrogen bonds along the other two axial directions.
