Abstract: The title complex, [NaSm(C₇H₅O₃)₄(C₁₂H₈N₂)₂]_n, is a heteronuclear polymer. The Sm and Na atoms are bridged by two carboxylate groups. The Sm atom is eightfold-coordinated by four N atoms of two bidentate phenanthroline ligands and four O atoms of four monodentate carboxyl groups. The Na and Sm atoms lie on a twofold axis. The carboxyl groups of the hydroxybenzoate ligands act as bridges between the Na and Sm atoms, forming a one-dimensional polymer. In addition, there are intramolecular hydrogen bonds between the phenol OH group and an adjacent carboxyl O atom.
