Novel Coordination Chemistry of Aluminum Borohydride

Abstract

Due to its high hydrogen content, aluminum borohydride(Al(BH4)3) (ABH) makes an attractive scaffold to build upon for ionic liquids used in rocket propulsion. Due to its highly pyrophoric nature ABH poses extreme handling hazards. This reactivity can be significantly tamed through the coordination of various ligands. Previously we investigated an IL based upon the [Al(BH4)4]- anion. This material showed a much improved air and moisture stability compared to ABH. Here we present research on the coordination of the cyanoborohydride anion (NCBH3-) with ABH. The coordination chemistry of this anion is by far more complex than that of the simple BH4- anion and led to the discovery of, new di- and tri-anions of aluminum.
