Abstract

Using 30% H 2 O 2 as the oxidant,the molybdate( NH 4) 6 [CO 2 Mo 10 O 38 H 4 ]·11H 2 O were obtained by reacting of( NH 4) 6 Mo 7 O 24 ·6H 2 O and CoCl 2 in aqueous solution by one- step method,and the structure and properties were characterized through single X- ray diffraction,IR and UV- Vis. The salt crystallized in the monoclnic space group a = 10. 826( 7) ,b = 12. 258( 9) ,c = 15. 548( 10) ,β = 95. 475( 10) °,V = 2053. 7( 2) 3,Z =4,D c = 3. 01 g· cm- 3,R 1 = 0. 0257,wR 2 = 0. 0656( I 2σ),and GOF = 1. 082.
