Molecular Structure and Photoluminescence of Square-anitiprismatic Europium Octahydrate Cations in [Eu(H2O)8]2 [V10O28]·8H2O Crystallines
[Eu(H2O)8]3+ cations in [Eu(H2O)8]2[V10O28]·8H2O form an approximately square-antiprismatic configuration. This configuration provides another model for the Eu3+ aqua ion in aqueous solutions. The lifetime of the 5D0 state for [Eu(H2O)8]3+ is 0.13 ± 0.01 ms at 4.2K, leading to a validity of the lumi...

Summary: | [Eu(H2O)8]3+ cations in [Eu(H2O)8]2[V10O28]·8H2O form an approximately square-antiprismatic configuration. This configuration provides another model for the Eu3+ aqua ion in aqueous solutions. The lifetime of the 5D0 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 2.5Å). |
