Ionic Liquids Heavy pnictogen tricyanides form amorphous polymers in the solid state. In their Communication on page 16012 ff., A. Schulz et al. show that this polymer formation can be avoided by using ionic liquids (e.g., [BMIm][OTf]) as reaction media due to formation of [E(CN) 3 X] − ions (E=Sb, Bi; X=OTf − ), which prevent E(CN) 3 from polymerizing. From these molecular [E(CN) 3 X] − ions, neutral E(CN) 3 species can be extracted with a polar organic solvent, such as THF, leading to the isolation of E(CN) 3 THF adducts.
