“…The absorption bands in the range of 513-525 cm -1 in all three complexes fall in the region reported for Cu-O bond vibrations, [26] while the absorption bands in the frequency range 432-465 cm -1 are due to the ν Cu-N vibrations. [27] Crystal structure data and structure refinement details for compounds 1, 2, and 3 are given in Table 2. The molecular structure of complex 1 is shown in Figure 1 and selected bond lengths and angles are listed in Table 1.…”

Dehydration and complexation reactions of [Y(TFA)3(H2O)3] (1; TFA = O2CCF3) were investigated with O‐ and N‐donor ligands in order to obtain suitable precursors for MOD (Metal Organic Deposition). Anhydrous adducts such as [Y2(μ,η2‐TFA)4(η1‐TFA)2(OHC2H4OiPr)4] (3), [Y2(μ,η2‐TFA)4(η1‐TFA)2(OHC2H4OC2H4OMe)2] (4), or [Y(TFA)3(triglyme)] (5) were isolated. The reactions with N‐donor ligands are more complex and afford mixed‐ligand derivatives such as [Y(TFA)3(H2O)2(LL)]m [LL = TMEDA (9), Me2NC2H4NMeC2H4NMe2 (10)] and, in the case of primary amines, yttrium oxohydroxo derivatives such as [H3O][Y3(μ3‐OH)(μ‐O)3(η1‐TFA)3(H2O)6(en)3] (6; en = NH2C2H4NH2). All complexes were characterized by elemental analysis, FT‐IR, and by single‐crystal X‐ray diffraction for 3, 4, and 6. All structurally characterized complexes contain on eight‐coordinate Y centers. Perfluorobutyrate and difluoroacetate derivatives were also prepared. (© Wiley‐VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2005)

The reactions between [Y(TFA)3(H2O)3] and either [Cu(TFA)2(MeOH)] or [Ba(TFA)2]∞ in the presence of excess N‐methyldiethanolamine (mdeaH2) have been investigated in relation with their use as precursors for high Tc superconductors. They afford the heterometallic Y3Cu complex [CuY3(μ3‐OH)(μ‐η3:η1‐mdeaH)3(μ3‐η3:η1:η1‐mdeaH)2(η2‐TFA)(μ,η2‐TFA)2](TFA)2(H2O) (1) and the homometallic Ba‐TFA 1D polymer [Ba3(η3‐mdeaH2)2(μ‐η3:η1‐mdeaH2)2(η1‐TFA)2(η2‐TFA)2(μ3‐η2:η2:η1‐TFA)2]1∞ (2), respectively, in high yield. These compounds were characterised by X‐ray diffraction and FT‐IR, ESR (for 1) and NMR (for 2) spectroscopy. Single‐crystal X‐ray diffraction studies show the versatile bonding modes of the trifluoroacetate and N‐methyldiethanolamine ligands, with the former acting not only as a terminal (η1 and η2) or bridging‐chelating (μ,η2 and μ3‐η2:η2:η1) ligand but also as a counterion, whereas the latter, either protonated or partially deprotonated, binds the metal centres in a chelating (η3) or bridging‐chelating (μ,η3:η1 and μ3‐η3:η1:η1) manner. The triangular Y3 unit [3.480(6)–3.550(6) Å] in the cation of 1 consists of one nine‐coordinate and two eight‐coordinate Y atoms, the former of which are quite scarce in alkoxide chemistry. The unique feature of the 1D polymeric structure of 2 is the secondary F···cation bond, which has not been observed so far for TFA ligands. In addition, it is the only example where the Ba atom is linked to monodentate, bidentate and bridging trifluoroacetate ligands simultaneously. (© Wiley‐VCH Verlag GmbH & Co.
