In the title compound, [Sm(C7H5O2)3(C12H8N2)], the SmIII cation is coordinated by six O atoms from three bidentate 2-formylphenolate ligands and by two N atoms from 1,10-phenanthroline ligand. The resulting SmN2O6 coordination polyhedron is a distorted square antiprism. In the crystal, C-H...O interactions connect molecules into chains along the b-axis direction. In addition, [pi]-[pi] stacking interactions are observed with centroid-centroid distances in the range 3.6422 (13)-3.7329 (13) Å.
