A Dinuclear Zinc(Ⅱ) Complex Derived from a ‘Click' Ligand Containing Phenol, Pyridine and Triazole Donors
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)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, 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.
