Abstract

Abstract : An Eu-containing polyoxoniobate (CN3 H6 )7 K3 H17 {Eu3 (H2 O)9 Nb48 O138 (H2 O)6 }·40H2 O is obtained under the protection of citric acid, which is a triangular cylindrical entity and displays red emission. Abstract : A europium-containing isopolyoxoniobate with the formula (CN3 H6 )7 K3 H17 {Eu3 (H2 O)9 Nb48 O138 (H2 O)6 }·40H2 O is synthesized under the protection of citric acid. ESI-MS spectra show that the polyoxoanion structural unit {Eu3 (H2 O)9 [Nb48 O138 (H2 O)6 ]} 27− is intact in aqueous solution. Moreover, its solid-state luminescence displays a red emission with the long lifetime of 258 μs.
