Abstract 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 CdF₂ as 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 α = 14.6436(8), V = 3140.1(3) Å³, Z = 2, M_r = 2857.96, D_c= 3.023 g/cm³ and F(000) = 2668. The final R = 0.0653 and wR = 0.1880 for 586 observed reflections with I > 2σ(I). In the title complex, three adjacent Cd(II) centers are connected by three μ₃-bridging triazole ligands to form triagonal secondary building units (SBUs), which are further interconnected to form a three-dimensional skeleton with tetrahedral cages.

Key words： triazole crystal structure zeolite-like framework Cd(II) complex
