Abstract: The title compound, {[Ce(C₅H₆O₅)(H₂O)₄]Cl·2H₂O}_n, is a coordination polymer built up from binuclear units extending along [100] with the ligands as spacers. The complex polymers are held together by interlayer hydrogen bonds involving the counter-ion and the solvent water molecules embedded in the structure. The tetradentate glutarate dianion coordinates in a bridging-chelating mode, with one triply ligating O atom, and in a conventional carboxylate bridge to the water-coordinated Ce^III ion. In the centered cage assembly, two nine-coordinated Ce^III ions are linked through six oxo bridges.
