Abstract
The solvothermal reaction of lanthanide nitrate and H4Diida ligand (H4Diida = 2-(4,5-dicarboxy-1H-imidazol-2-yl)-1H-imidazole-4,5-dicarboxylic acid) in the presence of ammonium oxalate results in a new three-dimensional (3D) lanthanide-organic framework, namely, {[Pr(Ida)(μ2-C2O4)0.5(H2O)2] · H2O}n (H2Ida = 1H-imidazole-4,5-dicarboxylic acid). H4Diida ligand can be in situ into Ida2− ions under the conditions, as unequivocally proved by these similar situations occurred in other systems. Single crystal X-ray diffraction analysis reveals the formation of a novel wave-like structure. It crystallizes in the monoclinic system, space group of P21/c. The polymer is built from two kinds of parallel alternately 1D infinite chain through the carboxylate double-linking adjacent Pr3+ cations, forming an extended 2D bilayer-like structure along the yz plane. Moreover, the polymer further stacks via weak interactions to generate a 3D supramolecular framework. The photoluminescence and magnetic properties for the polymer were also investigated and discussed.
