Abstract

We report a strategy of using small cations to construct ionic liquid octahydrotriborate. The novel liquid Li(NH₃)B₃H₈, prepared by a facile reaction of NH₄B₃H₈ with LiH, froze below −33.4 °C and crystallized into a monoclinic unit cell with lattice parameters of a = 8.813(1) Å, b = 8.8626(1) Å, c = 8.2076(1) Å, and β = 110.1046(5)°, providing a promising functional liquid octahydrotriborate with the highest B₃H₈⁻ content and lowest freezing temperature.
