Crystal structure of methyl 2-(7-hy-droxy-2-oxo-2H-chromen-4-yl)acetate.

ABSTRACT: 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, mol-ecules 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 inter-actions, thereby generating undulating (001) sheets.
