Abstract: The title polymeric compound, {[Eu₂Cu(C₇H₃O₄)₄(H₂O)₆]·2H₂O}_n, was prepared by a hydrothermal reaction at 453 K. The Eu^III ion has a double-capped trigonal prismatic coordination geometry with an NdNO₇ core, while the Cu^II ion is located on an inversion center and assumes a square-planar coordination geometry. The pyridine-2,5-dicarboxylate dianions bridge the Eu^III and Cu^II ions, forming a three-dimensional polymeric structure.
