The asymmetric unit of the title compound, C(20)H(18)O(8), contains two mol-ecules with small geometric differences. The dihedral angles between the benzene rings are 62.94 (12) and 59.99 (12)°. The dihedral angles between the carboxylate groups in the 2- and 3-positions are 81.72 (13) and 65.54 (15)°, respectively. However, the dihedral angles between the carboxylate groups in the 3' and 4'-positions are 67.24 (15) and 59.98 (17)°, respectively. ...[more]
