Medientyp: E-Artikel Titel: Sonochemical Reaction of [Fe(CO)5] with 1‐Methylimidazole in An Ionic Liquid: Formation of [(1‐Methylimidazole)6FeII](PF6)2 Beteiligte: Jacob, David S.; Kahlenberg, Volker; Wurst, Klaus; Solovyov, Leonid A.; Felner, Israel; Shimon, Linda; Gottlieb, Hugo E.; Gedanken, Aharon Erschienen: Wiley, 2005 Erschienen in: European Journal of Inorganic Chemistry Sprache: Englisch DOI: 10.1002/ejic.200400711 ISSN: 1434-1948; 1099-0682 Schlagwörter: Inorganic Chemistry Entstehung: Anmerkungen: Beschreibung: <jats:title>Abstract</jats:title><jats:p>The ionic liquid 1‐butyl‐3‐methylimidazolium hexafluorophosphate, (BMI<jats:sup>+</jats:sup>)(PF<jats:sub>6</jats:sub><jats:sup>−</jats:sup>), has been used as a solvent in the sonochemical reaction of 1‐methylimidazole and [Fe(CO)<jats:sub>5</jats:sub>] at 40−50 °C under air. The reaction afforded [(1‐methylimidazole)<jats:sub>6</jats:sub>Fe<jats:sup>II</jats:sup>](PF<jats:sub>6</jats:sub>)<jats:sub>2</jats:sub>, the structure of which was determined at 293 K by single‐crystal X‐ray diffraction methods. The salt crystallizes in the trigonal space group <jats:italic>P</jats:italic><jats:styled-content>$\bar 3$<jats:inline-graphic xmlns:xlink="http://www.w3.org/1999/xlink" xlink:href="graphic/tex2gif-ueqn-1.gif" xlink:title="equation image" /></jats:styled-content> with unit‐cell parameters of <jats:italic>a</jats:italic> = 11.4603(16) Å, <jats:italic>c</jats:italic> = 8.0172(11) Å, and <jats:italic>Z</jats:italic> = 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 Fe<jats:sup>2+</jats:sup>. (© Wiley‐VCH Verlag GmbH & Co.
