Abstract

This study examines the synthesis and properties of salts of the new tetrahedral [B(O–C2H4–CN)4] anion, which can be synthesized by the reaction of tetrahedral NaBH4 and HO–C2H4–CN followed by salt metathesis. The structures of M[B(O–C2H4–CN)4] [M = Na, 1-ethyl-3-methylimidazolium (EMIm), 1-butyl-3-methylimidazolium (BMIm), 1-octyl-3-methylimidazolium (OMIm), Me4N, Et4N, and Bu4N] as well as the thermal decomposition products are discussed.
