摘　　要：The salt, [Y（H2O）8]2[V10O28]·9H2O, contains two discrete water-groups coordinated Y（Ⅲ） cations, an isopoly complex ion, decavanadate （V10O28^6-） and nine additional water molecules, which are combined together by static electric forces and hydrogen bonds. The y^3＋ is eight-coordinated with a square antiprism geometry. The single-crystal X-ray analysis reveals that the crystal crystallizes in triclinic, space group P1^- with a = 9.1454 （18）, b = 10.007（2）, c = 12.772（3） A°, α= 68.86（3）, β = 77.50（3）, γ= 89.23（3）°, V= 1061.7（4）A°^3 and Z= 1.The salt, [Y（H2O）8]2[V10O28]·9H2O, contains two discrete water-groups coordinated Y（Ⅲ） cations, an isopoly complex ion, decavanadate （V10O28^6-） and nine additional water molecules, which are combined together by static electric forces and hydrogen bonds.
