In the title complex, [Eu2(C8H7O3)6(C12H8N2)2] n , which has an inversion center midway between two Eu(III) atoms of the structural unit, forms a one-dimensional polymer bridged by two mondentate, two bidentate, and two tridentate carboxylate groups with an Eu-Eu separation of 4.1853(7) Å. Each Eu atom is nine-coordinated by two N atoms of a 1,10-phenanthroline (phen) ligand and seven O atoms from six phenoxyacetate ligands, to form a distorted tricapped trigonal prismatic. The luminescence spectrum of the polymer indicates that the intensity of the emission wavelength at 619 nm is the strongest among all emission wavelengths and the second phen ligand shows an enhancement effect on the luminescence of the complex.
