N2 - The ionic liquid 1-butyl-3-methylimidazolium hexafluorophosphate, (BMI +)(PF6-), has been used as a solvent in the sonochemical reaction of 1-methylimidazole and [Fe(CO)5] at 40-50 °C under air. The reaction afforded [(1-methylimidazole)6Fe II] (PF6)2, the structure of which was determined at 293 K by single-crystal X-ray diffraction methods. The salt crystallizes in the trigonal space group P3 with unit-cell parameters of a = 11.4603(16) Å, c = 8.0172(11) Å, and Z = 1. The crystals showed twinning by merohedry, which was accounted for in the structure determination and refinement calculations. All the 1-methylimidazole ligands are equivalent, with a Fe-N bond length of 2.204(3) Å. Mössbauer spectroscopy confirmed the presence of Fe2+.
