摘要：

An aluminum-containing solvate ionic liquid, DMI-AlCl3 (1 M)-MgCl2 (0.5 M) was used as the electrolyte for magnesium electrodeposition. The results of Raman spectroscopy and Al-27 nuclear magnetic resonance spectroscopy indicated the existence of aluminum-containing [AlCl4](-) and [AlCl2(DMI)(4)](+) in the DMI-AlCl3 (1 M) system. When 0.5 M MgCl2 was added to DMI-AlCl3, the Mg(II) species was [MgCl(DMI)(n)](+). X-ray diffraction analysis indicated that a coating of Al3Mg2 can be prepared by potentiostatic electrodeposition at 1.45 V (vs. Al) at 323 K on a copper sheet cathode.
