Abstract

A europium-containing isopolyoxoniobate with the formula (CN<sub>3</sub>H<sub>6</sub>)<sub>7</sub>K<sub>3</sub>H<sub>17</sub>{Eu<sub>3</sub>(H<sub>2</sub>O)<sub>9</sub>Nb<sub>48</sub>O<sub>138</sub>(H<sub>2</sub>O)<sub>6</sub>}·40H<sub>2</sub>O is synthesized under the protection of citric acid. ESI-MS spectra show that the polyoxoanion structural unit {Eu<sub>3</sub>(H<sub>2</sub>O)<sub>9</sub>[Nb<sub>48</sub>O<sub>138</sub>(H<sub>2</sub>O)<sub>6</sub>]}<sup>27-</sup> is intact in aqueous solution. Moreover, its solid-state luminescence displays a red emission with the long lifetime of 258 μs.
