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.展开更多
