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 H2 L 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) A, β = 94.566(2)o, 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 structure of cation, the phenolate oxygen atoms of ligand act as the bridging nodes to form a rhombic Zn2(OAr)2 core.
