Abstract

( 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.
