An air-stable Mg salt, [Mg(MIm)(6)][TFSA](2) [MIm = 1-methylimidazole; TFSA = bis(trifluoromethylsulfonyl)amide], was obtained by recrystallization from the MIm solution of Mg[TFSA](2). This compound melts at 481 K under sealed conditions, whereas it loses MIm at elevated temperatures (448 K, 5% weight loss) under unsealed conditions. The crystal structure of [Mg(MIm)(6)][TFSA](2) was determined by X-ray diffraction. The compound crystallizes in the monoclinic system (space group P2(1)/c) with a = 8.2062(7) angstrom, b = 11.3185(10) angstrom, c = 24.454(2) angstrom, = 90.229(2)degrees, V = 2271.3(3) angstrom(3), and Z = 2. The Mg2+ cation is octahedrally surrounded by six non-methylated N atoms of MIm ligands to form the [Mg(MIm)(6)](2+) complex cation, in which three imidazolium rings are crystallographically independent. The interplanar angles between two imidazolium rings, which are close to 90 degrees in an ideal model, are 64.01(14), 72.86(18), and 81.91(17)degrees owing to the interaction of the [Mg(MIm)(6)](2+) cations with the TFSA(-) anions. The TFSA anion is completely isolated from the Mg2+ core and adopts the energetically favorable trans conformation. Raman spectroscopic measurements revealed the octahedral coordination of MIm to Mg2+ in crystalline [Mg(MIm)(6)][TFSA](2) and MIm solutions of Mg[TFSA](2).
