dc.description.abstractEnThe 2D composition-space diagram of the Al(OH)<sub>3</sub>−<i>Am</i><sub><i>2</i></sub><i>TAZ</i>−HF<sub>aq</sub>−ethanol system is established under microwave heating at 190 °C for [Al<sup>3+</sup>] = 1 mol·L<sup>−1</sup>. Four new fluoroaluminates are evidenced when the [HF]/[<i>Am</i><sub><i>2</i></sub><i>TAZ</i>] ratio is increased in the starting solution, and the dimensionality of the inorganic frameworks is increased from 0D in [H<i>Am</i><sub><i>2</i></sub><i>TAZ</i>]<sub>2</sub>·(AlF<sub>5</sub>(H<sub>2</sub>O))·2H<sub>2</sub>O (<i>Pc</i>, <i>Z</i> = 2), to 1D in [H<i>Am</i><sub><i>2</i></sub><i>TAZ</i>]<sub>2</sub>·(AlF<sub>5</sub>) and [H<i>Am</i><sub><i>2</i></sub><i>TAZ</i>]<sub>2</sub>·(Al<sub>2</sub>F<sub>8</sub>) (<i>Fdd</i>2, <i>Z</i> = 8), and to 2D in [H<i>Am</i><sub><i>2</i></sub><i>TAZ</i>]<sub>2</sub>·(Al<sub>5</sub>F<sub>17</sub>) (<i>Imm</i>2, <i>Z</i> = 2). This evolution is partially paralleled by the thermal decomposition of [H<i>Am</i><sub><i>2</i></sub><i>TAZ</i>]<sub>2</sub>·(AlF<sub>5</sub>(H<sub>2</sub>O))·2H<sub>2</sub>O; on heating, this hydrate gives [H<i>Am</i><sub><i>2</i></sub><i>TAZ</i>]<sub>2</sub>·(AlF<sub>5</sub>) at 100−150 °C and [H<i>Am</i><sub><i>2</i></sub><i>TAZ</i>]<sub>2</sub>·(Al<sub>2</sub>F<sub>8</sub>) at 180 °C; the loss and simultaneous decomposition of [H<i>Am</i><sub><i>2</i></sub><i>TAZ</i>]F leave a solid residue of polymeric paracyanogen (CN)<sub>2<i>n</i></sub> that is further decomposed and hydrolyzed into HCN and HNCO by atmospheric water traces. NMR <sup>19</sup>F spectroscopy of [H<i>Am</i><sub><i>2</i></sub><i>TAZ</i>]<sub>2</sub>·(AlF<sub>5</sub>) is in agreement with the crystallographic determination, and the <sup>27</sup>Al spectrum demonstrates that a significant F<sup>−</sup>/OH<sup>−</sup> substitution is excluded.
