Tetrakis[μ-2-(3,4-dimethoxyphenyl)acetato]- κ4O:O′;κ3O,O′:O;κ3O:O,O′bis{[2-(3,4-dimethoxyphenyl)acetato- κ2O,O′](1,10-phenanthroline-κ2N,N′)samarium(III)}

In the centrosymmetric dinuclear title complex, [Sm-2-( C10H11O4)(6)(C12H8N2)(2)], the Sm-III 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 1,10phenanthroline (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 center dot center dot center dot O hydrogen bond occurs. Intermolecular C-H center dot center dot center dot O interactions are also present in the crystal.
