A novel zeolite-like metal-organic framework,[Cd12(trz)12·F10·(SiF6)3]·(H3O)4(Htrz=1,2,4-triazole),has been synthesized under solvothermal conditions using 1H-1,2,4-triazole-3-carboxylic acid and CdF2as the starting materials.The complex has been characterized by elemental analysis,IR,SEM-EDS,gas adsorption,powder and single-crystal X-ray diffraction analyses.The title complex crystallizes in the cubic I-43m space group,with a=14.6436(8),V=3140.1(3)3,Z=2,Mr=2857.96,Dc=3.023 g/cm3and F(000)=2668.The final R=0.0653 and wR=0.1880 for586 observed reflections with I>2σ(I).In the title complex,three adjacent Cd(Ⅱ)centers are connected by threeμ3-bridging triazole ligands to form triagonal secondary building units(SBUs),which are further interconnected to form a three-dimensional skeleton with tetrahedral cages.
