Sumario: | The asymmetric unit of the title compound, C(12)H(12)O(6), contains two essentially identical molecules related by a pseudo-inversion centre. The three acetoxy groups in each molecule are essentially planar and are tilted, in a regular propeller-style arrangement, with their normals oriented between 56.72 (12) and 76.35 (9)° from the normal to the mean plane of the central C(6) ring; in each molecule the three carbonyl O atoms are on the same side of the C(6) ring, with the C(ring)—O—C—Me bonds in a trans conformation. The principal intermolecular contacts appear to be C—H⋯π-ring interactions; each C(6) ring has such a contact to both faces of the ring; in addition, each molecule has two intermolecular C—H⋯O contacts with H⋯O distances less than 2.55 Å. |
