Abstract: Two fluoro-bridged lanthanide-containing metal–organic frameworks (MOFs) were synthesized using 2,2′-bipyridine-4,4′-dicarboxylic acid (BPDC), a fluorinated modulator, and a lanthanide nitrate. The syntheses of MOFs containing Gd3+ or Tb3+ and a closely related MOF structure containing Ho3+, Gd3+, or Tb3+ are presented. The presence of the fluorinated metal chains in these MOFs is shown through single crystal X-ray diffraction, energy dispersion X-ray spectroscopy, 19F nuclear magnetic resonance, and X-ray photoelectron spectroscopy. Magnetic measurements reveal weak antiferromagnetic exchange between the Ln3+ ions mediated by fluoride anions along the zigzag ladder chains present in the crystal structures of these MOFs.

100% | With sodium hydroxide In ethanol; water at 20℃; for 0.166667 h; | Sodium 2,6-difluorobenzoate; To a solution of 2,6-difluorobenzoic acid (1.0Og1 6.3mmol) in EtOH and water (5:1 , 6OmL) was added 1 N aqueous sodium hydroxide solution (6.33mL, 6.3mmol). The reaction mixture was stirred for 10 minutes at room temperature and then solvents were removed in vacuo to yield sodium 2,6-difluorobenzoate (1.22g, 6.3mmol, quantitative) as an off white solid. 1H NMR (DMSO) δ 6.89 (2H, m), 7.15 (1 H, m). |
