Synthesis, Structure, Characterization, and Redox Properties of the Porous MIL‐68(Fe) Solid

Abstract A new porous Fe III ‐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 (H 2 BDC) 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, 57 Fe Mössbauer spectrometry, and electrochemical lithium insertion.
