organic compounds
In the title compound, 2,3,5,6-tetrahydrocyclopenta[1,2-e]naphtho[1,2-b]pyran-4(1H)-one, C16H14O2, the planar pyrone ring makes dihedral angles of less than 10° with the best planes of each of the other three rings. The maximum deviation for each of the planes through non-H atoms is less than 0.225 (4) Å. Molecules in the crystal are packed in columns. Molecular-dynamics calculations of the interaction energy between neighbouring molecules within the columns gave a rather large value, ca 25 kJ mol-1. Only weak interactions were found between the columns.
