Abstract

The title compound, C13H12Cl2O5, is an isocoumarin compound which has been isolated from the ethyl acetate extract of the fermentation broth of actinomycete Streptomyces sp. (V4) from the South China Sea. There are intra- and intermolecular hydrogen bonds and halogen bonds [Cl...Cl = 3.434 (2) Å; C—Cl...Cl = 121.6°]. The intermolecular O—H...O hydrogen bonds link molecules into chains along the b axis.
