Description
Summary:A new 3d–4f heterometallic polymer, poly[[aqua‐μ3‐chlorido‐[μ3‐4‐(pyridin‐4‐yl)benzoato]tris[μ2‐4‐(pyridin‐4‐yl)benzoato]dicopper(I)erbium(III)] dihydrate], {[Cu2Er(C12H8NO2)4Cl(H2O)]·2H2O}n, was synthesized by the hydrothermal reaction of Er2O3, CuCl2·2H2O and 4‐(pyridin‐4‐yl)benzoic acid in the presence of HClO4. The asymmetric unit contains one Er3+ cation, two Cu+ cations, one Cl− anion, four deprotonated 4‐(pyridin‐4‐yl)benzoate ligands, one coordinated aqua ligand and two solvent water molecules. This tubular one‐dimensional polymer is constructed from alternating clusters of europium(III)–water and copper(I) chloride bridged by 4‐(pyridin‐4‐yl)benzoate ligands. Extensive hydrogen‐bonding interactions involving both the coordinated and the solvent water molecules provide further stabilization to the structure.
