摘　　要：The title compound [Co(en) 2(H 2O) 2] 2· [Mo Ⅴ 4Mo Ⅵ 4V Ⅳ 8O 40 (AsO 4)] was synthesized by hydrothermal method and its structure was determined with single crystal X ray analysis. The cluster anion is a tetracapped Keggin polyanion, which contains different coordinated cations. The crystal is monoclinic, space group C2/c with a =1.458 3(2) nm, b =2.174 07(13) nm, c =1.893 2(2) nm, β =91.532°, V =6.000 2(10) nm 3, Z =2, D c=1.452 g/cm 3, R =0.035 9, R w=0.079 8, S =1.092.The title compound [Co(en) 2(H 2O) 2] 2· [Mo Ⅴ 4Mo Ⅵ 4V Ⅳ 8O 40 (AsO 4)] was synthesized by hydrothermal method and its structure was determined with single crystal X ray analysis.
