The effect of the coordination ability of the solvent species on the Mg plating/stripping behavior was investigated. The Mg plating reaction in Mg(N(CF 3 SO 2 ) 2 ) 2 /diglyme was inhibited by the equimolar of 15-crown-5 ether (15C5) to Mg 2+ -ion. On the other hand, Mg plating took place in the solution by reducing the amount of 15C5 less than that of Mg 2+ -ion. FT-IR spectra showed that 15C5 preferentially solvated Mg 2+ -ion in the glyme based solutions. The theoretical calculation indicated the interaction between Mg 2+ -ion and each O atom in 15C5 was stronger than that with diglyme or larger sized crown ether. The results showed that the coordination ability of the solvent species could be the critical for the Mg plating reaction.
