Title: Materials Data on Ca(BH4)2 by Materials Project

Abstract

Ca(BH4)2 crystallizes in the orthorhombic Pbca space group. The structure is three-dimensional. Ca2+ is bonded in a 10-coordinate geometry to ten H+0.50+ atoms. There are a spread of Ca–H bond distances ranging from 2.33–2.52 Å. There are two inequivalent B3- sites. In the first B3- site, B3- is bonded in a tetrahedral geometry to four H+0.50+ atoms. All B–H bond lengths are 1.23 Å. In the second B3- site, B3- is bonded in a tetrahedral geometry to four H+0.50+ atoms. There is two shorter (1.22 Å) and two longer (1.23 Å) B–H bond length. There are eight inequivalent H+0.50+ sites. In the first H+0.50+ site, H+0.50+ is bonded in a distorted L-shaped geometry to one Ca2+ and one B3- atom. In the second H+0.50+ site, H+0.50+ is bonded in a distorted single-bond geometry to one Ca2+ and one B3- atom. In the third H+0.50+ site, H+0.50+ is bonded in a distorted single-bond geometry to one Ca2+ and one B3- atom. In the fourth H+0.50+ site, H+0.50+ is bonded in a distorted single-bond geometry to two equivalent Ca2+ and one B3- atom. In the fifth H+0.50+ site, H+0.50+ is bonded in a distorted L-shaped geometry to one Ca2+ and one B3-more » atom. In the sixth H+0.50+ site, H+0.50+ is bonded in a distorted water-like geometry to one Ca2+ and one B3- atom. In the seventh H+0.50+ site, H+0.50+ is bonded in a distorted single-bond geometry to two equivalent Ca2+ and one B3- atom. In the eighth H+0.50+ site, H+0.50+ is bonded in a distorted water-like geometry to one Ca2+ and one B3- atom.« less
