【 摘 要 】

In the title compound, C17H12O5, the dihedral angle between the planes of the coumarin ring system (r.m.s. deviation = 0.015 Å) and the benzene ring is 48.04 (10)°. The central CO2 group subtends a dihedral angle of 27.15 (11)° with the coumarin ring system and 74.86 (13)° with the benzene ring. In the crystal, mol­ecules are linked by C—H⋯O inter­actions, which generate a three-dimensional network. Very weak C—H⋯π inter­actions are also observed.
