Materials Data on RbBH4 by Materials Project
RbBH4 crystallizes in the cubic F-43m space group. The structure is three-dimensional. Rb1+ is bonded in a 12-coordinate geometry to twelve equivalent H+0.50+ atoms. All Rb–H bond lengths are 3.00 Å. B3- is bonded in a tetrahedral geometry to four equivalent H+0.50+ atoms. All B–H bond lengths are 1.23 Å. H+0.50+ is bonded in a single-bond geometry to three equivalent Rb1+ and one B3- atom.
