Abstract

In the centrosymmetric dinuclear title complex, [Sm2(C10H11O4)6(C12H8N2)2], the SmIII ion is nine-coordinated by seven O atoms of five 2-(3,4-dimethoxyphenyl)acetate (DMPA) ligands and two N atoms of one bis-chelating 1,10-phenanthroline (phen) ligand, forming a distorted tricapped trigonal-prismatic environment. The DMPA ligands coordinate in bis-chelate, bridging and bridging tridentate modes. An intramolecular C—H...O hydrogen bond occurs. Intermolecular C—H...O interactions are also present in the crystal
