摘要：

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 40-50degreesC under air. The reaction afforded [(1-methylimidazole)(6)Fe-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 M with unit-cell parameters of a = 11.4603(16) Angstrom, c = 8.0172(11) Angstrom, 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) Angstrom. Mossbauer spectroscopy confirmed the presence of Fe2+. ((C) Wiley-VCH Verlag GmbH & Co.
