Abstract

Two new hybrid inorganic-organic frameworks containing perfluorinated dicarboxylate ligands have been synthesized ionothermally from a mixture of 1-ethyl-3- methylimidazolium bromide (emim-Br), and triflimide (emim-Tf2N). The cobalt(II) tetrafluorosuccinate, [emim](2)[Co(H2O)(2)(O2CCF2CF2CO2)(2)] (1), is a two-dimensional coordination polymer containing anionic framework layers separated by emim cations. When hexafluoroglutaric acid is used in similar reactions, [emim](2)[Co-3(O2CCF2CF2CF2CO2)(4)(H2O)(4)] (2) forms. Like 1, this phase contains anionic layers of cobalt and the fluorinated carboxylate separated by emim cations. These new phases represent the first examples of ionothermally synthesized materials using perfluorinated aliphatic carboxylates.
