A novel three-dimensional Zn(II) coordination polymer, Zn3(C2H2N3)4(SiF6), has been synthesized under solvothermal conditions using 1H-1,2,4-triazole-3-carboxylic acid and zinc fluoride as the starting materials. The complex has been characterized by elemental analysis, IR, TG analysis and single-crystal X-ray diffraction analysis. The complex crystallizes in the tetragonal 14/mmm space group with a = 11.592(0), c = 7.526(1) A~, V= 1011.3(2)A3, Z = 2, M,. = 610.46, D, = 2.005 g/cm3 and F(000) = 596. The final R = 0.0312 and wR = 0.067 for 319 observed reflections with 1 〉 20(/). In the title complex, the Zn centers are interconnected by μ3-bridging triazole ligands to form a microporous three-dimensional metal-organic framework.
