摘要：

The most remarkable aspect of the crystal structure of the title compound (systematic name: 3,4-dihydro-2,2-dimethyl-2H-naphtho[1,2-b]pyran-5,6-dione), C15H14O3, is that a pi-stacking interaction is present between the two naphthalene ring systems of symmetry-related molecules. Apart from these pi-pi interactions, different molecules are held together by weak C-H center dot center dot center dot O hydrogen-bonding interactions.
