Abstract: The title lanthanide-bdc complex, {[Lu₂(C₈H₄O₄)₃(H₂O)₈]·2H₂O}_n (bdc is benzene-1,4-dicarboxylate), was synthesized under hydrothermal conditions. In this complex, the Lu^III centers are eight-coordinated by four O atoms from three benzene-1,4-dicarboxylate ligands and four from water molecules. Lu^III ions are bridged by benzene-1,4-dicarboxylate anions in two modes, forming polymeric chains. These chains are further assembled into a three-dimensional supramolecular network by O-HO hydrogen-bonding interactions.
