Synthesis, structures, fluorescence and magnetism of two lanthanide metal-organic frameworks with CaF2 topology based on silicon-centered tetrahedral ligand
Two 3D multifunctional lanthanide metal-organic frameworks(MOFs), Pr(HTCPS)(H2O)·2DMF·C2H5OH·5H2O(JUC-93) and Pr3(TCPS)2(NO3)(H2O)4(DMA)2·2DMA·C2H5OH·3H2O(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.
