Liu Xue-me

Abstract

A new Waugh molybdate formulated as(NH4)2(C5H6N)4MnMo9O32·8H2O has been isolated by reacting of(NH4)6MnMo9O32·6H2O and pyridine in aqueous solution,and characterized by single X-ray diffraction,elemental analysis,IR and solid UV-Vis diffuse reflectance spectroscopy.Crystal structural analysis indicate that the title compound crystallizes in the monoclinic system with space group P21/c,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(I2σ),GOF=1.058.
