Tris(2-ethylamino)amine (tren) as template for the elaboration of fluorides: synthesis and crystal structures of [(C{sub 2}H{sub 4}NH{sub 3}){sub 3}NH].[Zr{sub 3}F{sub 16}(H{sub 2}O)], [(C{sub 2}H{sub 4}NH{sub 3}){sub 3}N]{sub 2}.[ZrF{sub 6}].[Zr{sub 2}F{sub 12}] and [(C{sub 2}H{sub 4}NH{sub 3}){sub 3}N].[TaF{sub 7}].F

Using tris(2-ethylamino)amine (tren) as a template, three new fluorides are obtained by solvothermal synthesis: [(C{sub 2}H{sub 4}NH{sub 3}){sub 3}NH].[Zr{sub 3}F{sub 16}(H{sub 2}O)] (I), [(C{sub 2}H{sub 4}NH{sub 3}){sub 3}N]{sub 2}.[ZrF{sub 6}].[Zr{sub 2}F{sub 12}] (II) and [(C{sub 2}H{sub 4}NH{sub 3}){sub 3}N].[TaF{sub 7}].F (III). The structure determinations are performed by single crystal technique. The structure of I consists of infinite spiral-like [Zr{sub 3}F{sub 16}(H{sub 2}O)]{sup 4-} chains connected by tetraprotonated [trenH{sub 4}]{sup 4+} cations which possess a plane configuration. In II, isolated [ZrF{sub 6}] octahedra or [Zr{sub 2}F{sub 12}] dimers are linked to organic cations by a tridimensional hydrogen bond network. In III, [TaF{sub 7}]{sup 2-} monocapped trigonal prisms and 'isolated' fluoride ions are connected by hydrogen bonds to template moieties. In II and III, every organic moiety is triprotonated [trenH{sub 3}]{sup 3+} with a 'spider' configuration. In the tantalum phase, the hydrogen bond network leads to the formation of a layered structure.
