摘要：

A europium-containing isopolyoxoniobate with the formula (CN3H6)(7)K3H17{ Eu-3(H2O)(9)Nb48O138(H2O)(6)}center dot 40H(2)O is synthesized under the protection of citric acid. ESI-MS spectra show that the polyoxoanion structural unit {Eu-3(H2O)(9)[Nb48O138(H2O)(6)]}(27-) is intact in aqueous solution. Moreover, its solid-state luminescence displays a red emission with the long lifetime of 258 mu s.
