摘要：

In the title molecule, C11H8O5, the non-H atoms of the coumarin unit are essentially coplanar; the methoxy and carboxylate groups form dihedral angles of 6.5 (4) and 6.7 (4)degrees, respectively, with this group. In the crystal structure, weak intermolecular C-H center dot center dot center dot O hydrogen bonds form chains of rings propagating in the [210] direction.
