摘要
首次合成了一个新的多金属簇化合物,通过元素分析、IR光谱、UV-VIS-NIR反射光谱、ESR谱以及单晶X-射线衍射对其进行了表征,晶体学参数为:三斜晶系,P-1空间群,a=11.5499(17),b=12.9776(16),c=20.3895(25),α=90.72(1)°,β=91.35(1)°,γ=111.43(1)°,V=2843.40(1237)3,化学组成为(C10H10N3)3PMo12O40。Keggin型聚阴离子[PMo12O40]3-与质子化的2,2'-二吡啶胺之间形成一个三维超分子网状结构。部分质子化的2,2'-二吡啶胺间因π-π作用诱导按Z型链规则排列。将(C10H10N3)3PMo12O40应用于电极修饰,在ClO-3的电催化还原反应中表现出优良的性能。
A new polyoxometalate( C10H10N3)3PMo12O40( compound 1) is reported. Compound 1 has been characterized by elemental analysis,IR spectroscopy,UV-VIS-NIR reflectance spectroscopy,ESR spectroscopy and X-ray diffraction. Crystallographic parameters are as follows: triclinic,space group P1. a = 11. 5499( 17) ,b = 12. 9776( 16) ,c = 20. 3895( 25) ,α = 90. 72( 1) °,β = 91. 35( 1) °,γ = 111. 43( 1) °,V = 2843. 40( 1237) 3. In the title compound,Keggin type polyanions [PMo12O40]3-and protonated 2,2'-dipyridylamine form a 3D network structure. However,part of the organic ligand 2,2'-dipyridylamine is arranged in two parallel Z type chains due to π-π stacking. Compound 1 has been incorporated in an electrode and exhibited excellent performance in the electrocatalytic reduction of ClO-3.
