'''1-Butyl-3-methylimidazolium tetrachloroferrate''' is a [[magnetic ionic liquid]]. It can be obtained from [[1-butyl-3-methylimidazolium chloride]] and [[ferric chloride]]. It has quite low water solubility.<ref>{{cite journal | title = Discovery of a Magnetic Ionic Liquid [bmim]FeCl<sub>4</sub> |author1=Satoshi Hayashi |author2=Hiro-o Hamaguchi|journal=[[Chemistry Letters]]|volume=33|year=2004|issue=18|pages=1590–1591|doi=10.1246/cl.2004.1590}}</ref><ref>{{cite journal|title=A new class of magnetic fluids: bmim[FeCl<sub>4</sub>] and nbmim[FeCl<sub>4</sub>] ionic liquids |author1=Satoshi Hayashi |author2=Satyen Saha |author3=Hiro-o Hamaguchi|journal=[[IEEE Transactions on Magnetics]]|volume=42|year=2006|issue=1|pages=12–14|doi=10.1109/TMAG.2005.854875 |bibcode=2006ITM....42...12H |s2cid=42347833 }}</ref>
Due to the presence of the [[high spin]] FeCl<sub>4</sub> [[anion]], the liquid is [[paramagnetism|paramagnetic]] and a [[magnetic susceptibility]] of 40.6 × 10<sup>−6</sup> emu g<sup>−1</sup> is reported. A simple small [[neodymium magnet]] suffices to attract the liquid in a test tube.
