| Outline of Final Research Achievements |
The solvation structure of magnesium ion (Mg2+) in an electrolyte consisting of a magnesium salt Mg(N(SO2CF3)2)2 and tetraglyme (G4) was investigated. In the electrolyte, Mg2+ and G4 form a 1:1 complex cation [Mg(G4)]2+. It was revealed that G4 and Mg(N(SO2CF3)2)2 form a thermally stable complex in the molar ratio of 1:1. The melting point of [Mg(G4)](N(SO2CF3)2)2 is 137 degree Celsius, and the complex decomposes at around 200 degree Celsius. The electrochemical deposition of Mg metal was successfully performed in an electrolyte consisting of [Mg(G4)](N(SO2CF3)2)2 and an ionic liquid N-methyl-N-propyl-pyrrolidinium bis(trifluoromethanesulfonyl)amide.
