- Abstract
Three lanthanide–organic polymers, {[Ln(μ 3-HPhIDC)(μ 2-C2O4)0.5(H2O)] · 2H2O} n (Ln = Nd (1), Sm (2), and Tb (3)), have been isolated from the reaction of 2-phenyl-1H-imidazole-4,5-dicarboxylic acid (H3PhIDC) with equal amount of Ln(III) salts under solvothermal condition with the rigid coligand oxalate. The three polymers, which are isomorphous and isostructural, have been structurally characterized by elemental analyses, IR spectroscopy, and single-crystal X-ray diffraction. Each exhibits a 3-D framework constructed from infinite 2-D layers joined by μ 2-C2O4, which are composed of μ 3-HPhIDC2− and trivalent lanthanide. Thermal properties have also been investigated.
