Materials Data on CsBeH3 by Materials Project
CsBeH3 is Potassium chlorate structured and crystallizes in the monoclinic P2_1/m space group. The structure is three-dimensional. Cs1+ is bonded in a 9-coordinate geometry to nine H1- atoms. There are a spread of Cs–H bond distances ranging from 3.08–3.32 Å. Be2+ is bonded in a trigonal planar geometry to three H1- atoms. All Be–H bond lengths are 1.40 Å. There are two inequivalent H1- sites. In the first H1- site, H1- is bonded in a distorted single-bond geometry to three equivalent Cs1+ and one Be2+ atom. In the second H1- site, H1- is bonded in a distorted single-bond geometry to three equivalent Cs1+ and one Be2+ atom.
