Abstract

Seven new partially fluorinated metal−organic frameworks (F-MOFs) have been synthesized under different solvothermal conditions (H2O or N,N-dimethylformamide (DMF)) from transition metal cations [Zn(II), Co(II), and Mn(II)], 1,10-phenanthroline (phen), and 4,4′-(hexafluoroisopropylidene) bis(benzoic acid) (C17H10F6O4, H2hfbba) to determine the influence of reaction conditions on the formation of metal−organic frameworks. This family of materials displays a striking degree of structural similarity depending on the solvent of synthesis. Of the seven materials, two contain three-dimensional connectivity: Co3(hfbba)6(phen)2 (F-MOF-6) and Mn3(hfbba)6(phen)2 (F-MOF-10). Three materials are one-dimensional structures: Zn(hfbba)0.5(phen)(HCO2) (F-MOF-8), Mn(Hhfbba)2(phen) (F-MOF-11), and [Mn(hfbba)2(dm-phen)]·(H2O) (F-MOF-11A). Lastly, Co(hfbba)(phen)2·2(H2hfbba)(H2O)(HCO2) (F-MOF-7) and Zn(hfbba)(phen)2·2(H2hfbba) (H2O)(HCO2) (F-MOF-9) are discrete zero-dimensional molecular complexes. F-MOF-6 and -10, which fea...
