The heavy pnictogen tricyanides, E(CN) 3 (E=Sb, Bi), were synthesized from EF 3 and Me 3 SiCN in ionic liquids, for example, 1‐butyl‐3‐methylimidazolium trifluoromethanesulfonate ([BMIm][OTf]), which prevents the oligomerization of the molecular E(CN) 3 species by formation of [BMIm][E(CN) 3 (OTf)] salts in solution. Recrystallization of [BMIm][E(CN) 3 (OTf)] from THF led to the isolation and full characterization of the molecular species E(CN) 3 ⋅ 2 THF.
