Abstract: The title compound [Co(en)2(H2O)2] 2· [Mo4Ⅴ Mo4Ⅵ V8Ⅳ O40 (AsO4)] 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=1.4583(2) nm, b=2.17407(13) nm, c=1.8932(2) nm, β=91.532°, V=6.0002(10) nm3, Z=2, Dc=1.452 g/cm3, R=0.0359, Rw=0.0798, S=1.092.

Key words: Hydrothermal synthesis, Tetracapped Keggin structure, Crystal structure
