Hydrothermal synthesis and crystal structures of two lanthanide coordination polymers with novel tetradentate-coordinated perchlorates

Two new 3D lanthanide coordination polymers {[Ln(C2O4)(ClO4)(H2O)] · Cl}n [Ln = Pr (1) and Nd (2)] have been synthesized by hydrothermal reactions and characterized by elemental analysis, X-ray single-crystal analyses, IR and Raman spectroscopy. X-ray crystal structure analyses reveal that compounds 1 and 2 are isostructural and crystallized in the space group P 21/c . A 1D zigzag chains formed by oxalate ligands in μ2-mode to bridge Ln(III) atoms present in the two complexes and the adjacent zigzag chains were further connected by μ3-η1:η1:η1:η1 fashion of View the MathML source
