【 摘 要 】

In the title coumarin derivative, C12H10O5, the fused ring system is almost planar (r.m.s deviation = 0.016 Å). The Car—C—C=O torsion angle of the side chain is −8.4 (2)° In the crystal, mol­ecules are linked by O—H⋯O hydrogen bonds, generating C(8) chains propagating in the [100] direction. The chains are cross-linked by weak C—H⋯O inter­actions, thereby generating undulating (001) sheets.
