Grid Constructed by Chain-Like Lanthanide(III) Acetate and Bridging Sulfate Ion: Synthesis, Crystal Structure, Thermal Stability and Luminescent Property

Five complexes of [Ln(OAc)SO4(H2O)2]n (HOAc = acetic acid, Ln = La-1, Pr-2, Nd-3, Sm-4, Eu-5) were hydrothermally synthesized. The three-dimensional supramolecular frameworks of title compounds are constructed by the layer of [Ln(OAc)SO4(H2O)2]n via the interlayer hydrogen bonding. The compound 5 exhibits strong red fluorescence in the visible region.
