摘要：

[Eu(H2O)(8)](3+) cations in [Eu(H2O)(8)](2)[V10O28]. 8H(2)O form an approximately square-antiprismatic configuration. This configuration provides another model for the Eu3+ aqua ion in aqueous solutions. The lifetime of the D-5(0) state for [Eu(H2O)(8)](3+) is 0.13 +/- 0.01 ms at 4.2K, leading to a validity of the luminescence lifetime method for the determination of the number of bonded water molecules (within the Eu-O distances of 2.5 Angstrom).
