Rare-earth trishexafluoroacetylacetonates and related compounds

Luminescence and Single‐Molecule‐Magnet Behaviour in Lanthanide Coordination Complexes Involving Benzothiazole‐Based Tetrathiafulvalene Ligands

“…The precursors Ln(hfac) 3 ·2H 2 O, Ln(tta) 3 ·2H 2 O, [57,58] [43] 4,5-(ethylenedithio)tetrathiafulvalene [59] and 2-(5-bromopyridin-2-yl)-1,3-benzothiazole, [60,61] were synthesized by previously reported methods. All other reagents were purchased from Aldrich Co., Ltd. and used without further purification.…”

Slow Magnetic Relaxation in Unprecedented Mono-Dimensional Coordination Polymer of Ytterbium Involving Tetrathiafulvalene-Dicarboxylate Linker

“…The precursor Yb(hfac) 3¨2 H 2 O (hfac´= 1,1,1,5,5,5-hexafluoroacetylacetonate anion) and the ligand Na 2 L were synthesized following previously reported methods [34,35]. All other reagents were commercially available and used without further purification.…”

Field-Induced Dysprosium Single-Molecule Magnet Involving a Fused o-Semiquinone-Extended-Tetrathiafulvalene-o-Semiquinone Bridging Triad

“…The precursors Dy(hfac)3·2H2O (hfac − = 1,1,1,5,5,5-hexafluoroacetylacetonate anion) [41] and the 2,2′-benzene-1,4-diylbis(6-hydroxy-4,7-di-tert-butyl-1,3-benzodithiol-2-ylium-5-olate biradical triad [22] (L) were synthesized following previously reported methods. All other reagents were purchased from Aldrich Co., Ltd. (Saint-Quentin Fallavier, France) and were used without further purification.…”
