Abstract
In the crystal structure, the title compound, C(24)H(22)O(8), lies on a twofold rotation axis and the asymmetric unit comprises one half-molecule. The dihedral angle formed by the coumarin unit with the symmetry-related part is 74.78 (14)degrees. One of the methoxy groups attached to the coumarin unit is considerably twisted, making an angle of 87.17 (17)degrees with respect to the coumarin unit; the other is twisted by 0.66 (19)degrees. No classical hydrogen bonds are found in the sturcture; only a weak C-H center dot center dot center dot pi interaction and short intramolecular O center dot center dot center dot O contacts [2.683 (2)-2.701 (2) angstrom] are observed.
