Conservation of [(C2H4NH3)3N]2·(ZrF7)2·H2O layers during the topotactic dehydration of [(C2H4NH3)3N]2·(ZrF7)2·9H2O

Hydrogen bonded H3O+, H2O, HF, F− in fluoride metalates (Al, Cr, Fe, Zr, Ta) templated with tren (tris-(2-aminoethyl)amine)

“…Numerous fluorides crystallise when tren amine (tris-(2-aminoethyl)amine) reacts with metal oxides, hydroxides or fluorides and aqueous HF in solvothermal conditions at low temperature [1][2][3][4][5][6][7][8]. According to the HF aqÁ content, the amine is tri-or tetra-protonated and the corresponding [H 3 associated entities is discussed in the article, together with the thermal stability of the solids.…”
