Title: Materials Data on Ca(AlH4)2 by Materials Project

Abstract

Ca(AlH4)2 crystallizes in the monoclinic P2_1/c space group. The structure is three-dimensional. Ca2+ is bonded in a 10-coordinate geometry to ten H1- atoms. There are a spread of Ca–H bond distances ranging from 2.33–2.58 Å. Al3+ is bonded to six H1- atoms to form edge-sharing AlH6 octahedra. There are a spread of Al–H bond distances ranging from 1.68–1.83 Å. There are four inequivalent H1- sites. In the first H1- site, H1- is bonded in a distorted T-shaped geometry to one Ca2+ and two equivalent Al3+ atoms. In the second H1- site, H1- is bonded in a 1-coordinate geometry to two equivalent Ca2+ and one Al3+ atom. In the third H1- site, H1- is bonded in a 1-coordinate geometry to two equivalent Ca2+ and one Al3+ atom. In the fourth H1- site, H1- is bonded in a water-like geometry to two equivalent Al3+ atoms.
