摘　　要：以(NH4)6Mo7O24和MnCl2为原料,质量分数为30%的H2O2为氧化剂,在室温下采用常规的水溶液法制备了(NH4)6MnMo9O32·9H2O,产率达到85%,并对其进行了X-射线单晶结构测定及元素分析、红外光谱和磁化率表征。晶体学参数为:三方晶系,空间群R32,晶体学参数为:a=15.98(19)A,b=15.98(19)A,c=12.40(3)A,V=2 747.6(8)A3,Z=3,Dc=3.116 g·cm-3,R1=0.043 2,wR2=0.105 5(I>2σ),GOF=1.022。( NH4)6MnMo9O32·9H2O was synthesized by the reaction of( NH4)6Mo7O24and MnCl2and using H2O2aqueous solution of 30% as oxidant at room temperature,and its yield reaches to 85%. Its structure and properties are characterized through X-ray diffraction,elemental analysis,IR and magnetic susceptibility. The results show that it is trigonal system of the space group R32,and it has the crystallographic parameters of a = 15. 98( 19) A,b = 15. 98( 19) A,c = 12. 40( 3) A,V = 2 747. 6( 8) A3,Z =3,Dc= 3. 116 g· cm- 3,R1= 0. 043 2,wR2= 0. 105 5( I > 2σ),GOF = 1. 022.
