Abstract

The first example of metal hydrazinoborane, LiN₂H₃BH₃, and its hydrazine borane adduct LiN₂H₃BH₃·2N₂H₄BH₃ were synthesized with their crystal structures successfully determined. The metal hydrazinoboranes exhibit dramatically improved dehydrogenation over the pristine hydrazine borane (N₂H₄BH₃) with nearly complete dehydrogenation in a mild temperature range (50–225 °C) and high purity of H₂ release.
