摘　　要：A novel 1,2,3-triazolyl-containing ligand （H2L） with long donor arms extending from the central pyridyl linker was synthesized by click cycloaddition of 2,6-bis（azidomethyl）pyri- line and 2-（（prop-2-yn-1-yl（pyridin-2-ylmethyl）amino）methyl）phenol. Further treatment of the igand H2L with zinc（II） perchlorate in the presence of triethylaminc, followed by anion exchange vith Na[BPh4], provided a dinuclear zinc（II） complex [Zn2L][BPh4]E-2DMF （1）. Complex 1 crystallizes in monoclinic, space group P21 with a = 10.4873（4）, b = 14.9078（5）, c = 25.8620（9） A, = 94.566（2）°, V = 4030.5（2） A3, Z = 2,μ= 0.657 mm-1, Dc = 1.324 Mg/m3, T = 296（2） K, C93H91N13B2O4Zn2, Mr = 1607.19, F（000） = 1684, S = 0.958, R = 0.0271 and wR = 0.0607. In the tructurc of cation, the phenolate oxygen atoms of ligand act as the bridging nodes to form a hombic Zn2（OAr）2 core.A novel 1,2,3-triazolyl-containing ligand （H2L） with long donor arms extending from the central pyridyl linker was synthesized by click cycloaddition of 2,6-bis（azidomethyl）pyri- line and 2-（（prop-2-yn-1-yl（pyridin-2-ylmethyl）amino）methyl）phenol.
