Abstract
A new porous FeIII-based MOF, formulated Fe(OH)(BDC)·(dmf)x with x ≈ 1.1 and presenting the MIL-68 topology, was prepared by reaction of an iron(III) salt and terephthalic acid (H2BDC) in N,N′-dimethylformamide (dmf) under acidic conditions. The structure and properties of this solid were studied by means of X-ray diffraction, thermogravimetric analysis, nitrogen sorption, 57Fe Mössbauer spectrometry, and electrochemical lithium insertion.
