Abstract

Synthetic approaches are presented for the isolation of r-/c-M(BH4)3 (M = La, Ce). The cubic c-Ce(BH4)3 (Fm3̅c) contains empty voids (∼59 Å3) in the open framework structure. Additionally, M(BH4)3 can be combined with LiCl in an addition reaction to form Li4[M4(BH4)12Cl4], containing the unique tetranuclear cluster [M4(BH4)12Cl4]4− and shows high Li-ion conductivity. This reaction pathway opens a way to synthesize a series of A4[M4(BH4)12X4] compounds with different anions (X) and metal ions (A).
