Molecular E(CN)3 (E=Sb, Bi) Species Synthesized from Ionic Liquids as Solvates.
The heavy pnictogen tricyanides, E(CN)3 (E=Sb, Bi) were synthesized from EF3 and Me3 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.
