(Z)-2-(2-Hydroxy-4-methoxybenzylidene)-1-benzofuran-3(2H)-one

Abstract

In the title compound, C16H12O4, the 1-benzofuranone unit is in a planar conformation [C—C—C—C = 179.69 (12)°]. The conformation around the C=C double bond [1.3370 (17) Å] is Z. In the crystal, the molecules are stabilized by O—H...O (running parallel to the bc plane) and C—H...O hydrogen bonds.
