The title compound, C7H4O3, is the first cyclic carbonate of an aromatic diol whose structure has been elucidated by means of single-crystal X-ray analysis. The molecule possesses crystallographic twofold rotation symmetry and non-crystallographic C2v symmetry. The C—O single bonds are slightly longer than those in comparable cyclic carbonates derived from aliphatic vicinal diols. The crystal structure is built up from columns of π-stacked molecules; the inversion-related molecules are stacked along the b axis, with the centroids of the benzene rings separated by 3.631 (1) Å.
