A Mg(II)‐based coordination polymer was synthesized by a solvothermal reaction between Mg 2+ and 2,5‐dimercaptoterephthalic acid (H 4 dmtp) in N , N ‐diethylformamide (DEF). The thiol (─SH) groups in the H 4 dmtp ligand were oxidized to form the sulfinato (─SO 2 − ) groups, which were structurally stabilized through coordination to the Mg 2+ centers. The temperature‐dependent proton conductivities exhibited relatively low activation energy (0.19 eV) for proton transfer, suggesting that the hydrogen‐bonded networks formed by the water molecules and the sulfinato oxygen atoms produced efficient proton‐hopping pathways.
