Materials Data on Y(BH4)3 by Materials Project
Y(BH4)3 crystallizes in the cubic Pa-3 space group. The structure is three-dimensional. Y3+ is bonded in a distorted q6 geometry to twelve H+0.50+ atoms. There are a spread of Y–H bond distances ranging from 2.28–2.35 Å. B3- is bonded in a tetrahedral geometry to four H+0.50+ atoms. All B–H bond lengths are 1.23 Å. There are four inequivalent H+0.50+ sites. In the first H+0.50+ site, H+0.50+ is bonded in a distorted single-bond geometry to one Y3+ and one B3- atom. In the second H+0.50+ site, H+0.50+ is bonded in a distorted single-bond geometry to one Y3+ and one B3- atom. In the third H+0.50+ site, H+0.50+ is bonded in a distorted single-bond geometry to one Y3+ and one B3- atom. In the fourth H+0.50+ site, H+0.50+ is bonded in a distorted single-bond geometry to one Y3+ and one B3- atom.
