以(NH4)6MnMo9O32·6H2O和吡啶为原料,采用常规的水溶液法首次合成了质子化的吡啶阳离子作为抗衡离子的Waugh型钼酸盐(NH4)2(C5H6N)4MnMo9O32·8H2O,对其进行了单晶结构测定、元素分析、红外光谱及固体紫外可见漫反射光谱表征.晶体学参数为:单斜晶系,P21/c空间群,a=2.180 5(17)nm,b=1.439 4(11)nm,c=1.570 7(12)nm,β=106.68(10)°,V=4.722 5(6)nm3,Z=4,Dc=3.386g/cm3,R1=0.058 6,wR2=0.183 1(I>2σ),GOF=1.058.
A novel Waugh molybdate (NH4) 2 (C5H6N) 4MnMo9O32 · 8H2O protonated pyridine cation was synthesized by the conventional aqueous method using (NH4) 6MnMo9O32 · 6H2O and pyridine as raw materials. Crystal structure determination, elemental analysis, infrared spectroscopy and solid-state UV-visible diffuse reflectance spectroscopy.The crystallographic parameters are: monoclinic, P21 / c space group, a = 2.180 5 (17) nm, b = 1.439 4 (11) nm = 3, Z = 4, Dc = 3.386g / cm3, R1 = 0.058 6, wR2 = 0.183 1 (I > 2σ), GOF = 1.058.
