摘　　要：以(NH4)6MnMo9O32和盐酸胍为前体原料,采用常规的水溶液法制备了Waugh型钼酸盐(CH6N3)6MnMo9O32·4H2O,并对其进行了红外光谱、紫外可见光谱、元素分析及单晶结构表征.晶体学参数为:四方晶系,P4(3)2(1)2空间群,a=16.51(13)A,b=16.51(13)A,c=17.40(18)A,V=4 742.4(7)A3,Z=4,D c=2.547 g·cm-3,R1=0.036 6,wR2=0.083 5(I>2σ),GOF=1.054.A new Waugh molybdate( CH6N3)6MnMo9O32 ·4H2O is prepared by the reaction of( NH4)6 MnMo9O32·6H2O with guanidine hydrochloride in aqueous solution. Its structure and properties are characterized through single X-ray diffraction,IR and UVVis. The salt crystallizes in the tetragonal space group P4(3)2(1)2 with a = 16. 51( 13)A,b = 16. 51( 13)A,c = 17. 40(18)A,V = 4 742. 4(7)A3,Z = 4,Dc = 2. 547 g·cm-3,R1 = 0. 036 6,wR2 = 0. 083 5( I > 2σ),GOF = 1. 054.
