Three New Lanthanide Coordination Polymers Built from H2bpdc Ligands: Syntheses, Structures, and Properties

Three new lanthanide‐organic coordination polymers, {[Ln2(bpdc)2(H2O)6(NO3)]·NO3} [Ln = La (1), Ce (2), Pr (3)] (H2bpdc = 2, 2′‐bipyridine‐6, 6′‐dicarboxylic acid) were synthesized under hydrothermal conditions and structurally characterized by elemental analysis, IR spectroscopy as well as single‐crystal and powder X‐ray diffraction. Single‐crystal X‐ray diffraction analysis revealed that compounds 1–3 are isostructural, composed of two dimensional honeycomb network linked by bpdc ligands. The magnetic property of compound 3 was investigated.
