We report a new sulfonamide–terephthalate linker, 2,5‐di(methylsulfonamido)terephthalic acid (H 4 ‐DSATA), and its incorporation into a MIL‐88B‐type mixed‐valence iron MOF, [(Fe 2+ Fe 3+ 2 )(μ 3 ‐O)(H 2 ‐DSATA) 3 •3DMF]. Despite mixed‐valence Fe nodes and a redox‐active ligand environment, the framework shows limited electronic transport, which DFT attributes to strong electronic‐state localization near the Fe─O units.
