摘要：
Solvothermal reaction of Pr(NO3)(3)center dot 6H(2)O with 2-methyl-1H-imidazole- 4,5-dicarboxylic acid (H3MIDC) and ammonium oxalate affords a metal-organic framework, {[Pr-2(mu(3)-HMIDC)(2)(mu(2)-C2O4)(H2O)(3)]center dot EtOH center dot 3H(2)O}(n) (1), which has been structurally characterized by single-crystal X-ray diffraction. Polymer 1 exhibits a novel 3D structure, in which infinite 1D chains, composed of nine-coordinated Pr(III) ions and oxalates, were linked by mu(3)-HMIDC2- to give rise to a 3D architecture. Its thermal and solid-state fluorescence properties have been investigated.
