摘要：

Two 3D multifunctional lanthanide metal-organic frameworks(MOFs), Pr(HTCPS)(H2O)center dot 2DMF center dot C2H5OH center dot 5H(2)O(JUC-93) and Pr-3(TCPS)(2)(NO3)(H2O)(4)(DMA)(2)center dot 2DMA center dot C2H5OH center dot 3H(2)O(JUC-94)[H4TCPS=tetrakis(4-carboxyphenyl)silane, DMF=N,N'-dimethylformamide, DMA=N,N'-dimethylacetamide and JUC=Jilin University China] were synthesized by the self-assembly of a rigid silicon-centered tetrahedral carboxylate ligand H4TCPS and Pr(III) ions in different solvothermal reactions. X-Ray crystallography revealed that they exhibited a rare CaF2 topology framework, constructed from the 4-connected tetrahedral TCPS unit with the 8-connected dinuclear praseodymium cluster unit and trinuclear praseodymium cluster unit, respectively. In addition, the luminescent and magnetic properties of the two compounds were investigated.
