以3-吡啶双三氮唑(H_2L)为有机连接子,利用水热环境进行自组装,获得了一个二维Ag(I)配位聚合物:[Ag4(H_2L)(HL)(PMo12O40)]·2H_2O.单晶X-射线衍射测定得该配合物为三斜晶系,P 1空间群,a=13.035(5),b=13.714(5),c=16.606(6),α=97.835(7)°,β=92.547(7)°,γ=107.895(4)°,Z=2,V=2786.9(18)3,Mr=2715.19,Dc=3.236 g/cm3,μ=4.113 mm-1,F(000)=2532,S=1.016,R=0.1556,wR=0.4692.配合物中,四种配位环境的Ag+通过两种配位模式的3-吡啶双三氮唑配体连接成一维金属-有机带,相邻的金属有机带通过三连接的多酸阴离子PMo12O403-拓展成二维配位聚合物网络.该配合物对亚甲基蓝在紫外光下的光催化性能也被研究.
A two dimensional Ag (I) coordination polymer [Ag4 (H_2L) (HL) (PMo12O40)] was obtained by the self - assembly of 3 - pyridine bistriazole (H_2L) · 2H 2 O. Single crystal X-ray diffraction showed that the complex was triclinic with space group P 1, a = 13.035 (5) , b = 13.714 (5) and c = 16.606 = 97.835 (7) °, β = 92.547 (7) °, γ = 107.895 (4) °, Z = 2, V = 2786.9 183, Mr = 2715.19, Dc = 3.236 g / cm3, μ = 4.113 In the complex, the four coordination environments of Ag + were determined by two coordination patterns of 3-pyridinedicotiazole ligands To form a one-dimensional metal-organic band, and the adjacent metal-organic bands extend to the two-dimensional coordination polymer network through the triple-linked polyacid anion PMo12O403-. The photocatalytic activity of this complex to methylene blue under UV light has also been studied.
