%X In the title dinuclear complex, [Tb2(C8H7O3)6(C12H8N2)2], each TbIII ion is eight-coordinated by two N atoms from a 1,10-phenanthroline ligand and six O atoms from the carboxylate groups of five 4-methoxybenzoate ligands in a distorted square-antiprismatic geometry. All six 4-methoxybenzoate ligands act in a bidentate mode, two coordinating to one Tb center each and the other four bridging two Tb centers [Tb...Tb separation = 4.3144 (6)  ]. In the crystal, intermolecular ¦Ð¨C¦Ð interactions between the aromatic rings of 1,10-phenanthroline and 4-methoxybenzoate ligands [centroid¨Ccentroid distance = 3.742 (9)  ] link two molecules into a centrosymmetric dimer. Weak intermolecular C¡ªH...O hydrogen bonds help to consolidate the crystal packing.
