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)pyridine and 2-((prop-2-yn-1-yl(pyridin-2-ylmethyl)amino)methyl)phenol. Further treatment of the ligand H₂L with zinc(Ⅱ) perchlorate in the presence of triethylamine, followed by anion exchange with Na[BPh₄], provided a dinuclear zinc(Ⅱ) complex [Zn₂L][BPh₄]₂·2DMF (1). Complex 1 crystallizes in monoclinic, space group P2₁ with a=10.4873(4), b=14.9078(5), c=25.8620(9) Å, β=94.566(2)°, V=4030.5(2) Å³, Z=2, μ=0.657 mm^-1, D_c=1.324 Mg/m³, T=296(2) K, C₉₃H₉₁N₁₃B₂O₄Zn₂, M_r=1607.19, F(000)=1684, S=0.958, R=0.0271 and wR=0.0607. In the structure of cation, the phenolate oxygen atoms of ligand act as the bridging nodes to form a rhombic Zn₂(OAr)₂ core.
