研究了溶剂种类的配位能力对镀/剥离Mg行为的影响。15-冠-5醚（15C5）对mg2 +离子的等摩尔量抑制了Mg (N (CF 3 so2) 2) 2/二lyme中的镀Mg反应。另一方面，溶液中15C5的减少量小于mg2 +离子的减少量，从而镀Mg。傅里叶变换红外光谱表明，15C5在glyme基溶液中优先溶解了mg2 +离子。理论计算表明，mg2 +离子与15C5中各O原子的相互作用强于与二甘醚或大尺寸冠醚的相互作用。结果表明，溶剂种类的配位能力可能是镀镁反应的关键因素。
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.
