摘要：

The first room temperature molten salts containing hexafluorometallate anions of transition metals, 1-ethyl-3-methylimidazolium (EMIm) hexafluoroniobate, EMImNb(V)F-6, and hexafluorotantalate, EMImTa(V)F-6, have been synthesized by the reactions of EMImF(.)2.3HF with NbF5 and TaF5, respectively. They exhibit similar physical properties. Viscosities and conductivities are 49 cP and 8.5 mS cm(-1) for ENImNbF(6) and 51 cP and 7.1 mS cm(-1) for EMImTaF(6), respectively at 298 K.
