Abstract

A Mg(II)-based coordination polymer was synthesized by a solvothermal reaction between Mg²⁺ and 2,5-dimercaptoterephthalic acid (H₄dmtp) in N,N-diethylformamide (DEF). The thiol (─SH) groups in the H₄dmtp ligand were oxidized to form the sulfinato (─SO₂⁻) groups, which were structurally stabilized through coordination to the Mg²⁺ 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.
