The title compound, C 28 H 20 O 4 , was synthesized by a bimolecular Zn–HCl reduction in glacial acetic acid using the meth­oxy-substituted xanthone as a starting material. The crystal structure shows that the 2,2′-meth­oxy­bixanthenyl­idene unit is an  E -type conformation  anti -folded conformer. The mol­ecule lies on an inversion center. The meth­oxy group is almost coplanar with the attached benzene ring, with a C—O—C—C torsion angle of 179.38 (14)°.
