Á2C 2 H 6 O, was synthesized by the reaction of benzene and pyromellitic acid dianhydride. The acid molecule is centrosymmetric. There are intermolecular O-HÁ Á ÁO hydrogen bonds and C-HÁ Á Á interactions in the crystal structure.
The centrosymmetric title compound, [Na(H 2 O) 3 ] 2 -(C 22 H 12 O 6 )Á4H 2 O, was prepared by slow evaporation of an aqueous solution of sodium dibenzoylterephthalate. The uncoordinated water molecules are connected by intermolecular O-HÁ Á ÁO hydrogen bonds.
