In the dimeric centrosymmetric title complex, [Er₂(C₁₀H₁₁O₄)₆(C₁₂H₈N₂)₂], the Er^III ion is nine-coordinated by five 2-(3,4-dimethoxylphenyl)acetic acid (DMPA) ligands via seven O atoms and two N atoms from a bis-chelating 1,10-phenanthroline (phen) ligand in a distorted tricapped trigonal-prismatic geometry. The DMPA ligands are coordinated to the Er^III ion in bis-chelate, bridging and bridging tridentate modes. Relatively weak intramolecular C-HO interactions reinforce the stability of the molecular structure. Intermolecular C-HO interactions are also observed.
