Materials Data on CsH3O2 by Materials Project

Abstract

CsH3O2 crystallizes in the tetragonal I4_1/amd space group. The structure is three-dimensional. Cs1+ is bonded to twelve H1+ atoms to form a mixture of distorted edge, face, and corner-sharing CsH12 cuboctahedra. There are eight shorter (3.04 Å) and four longer (3.10 Å) Cs–H bond lengths. There are two inequivalent H1+ sites. In the first H1+ site, H1+ is bonded in a linear geometry to four equivalent Cs1+ and two equivalent O2- atoms. Both H–O bond lengths are 1.23 Å. In the second H1+ site, H1+ is bonded in a linear geometry to four equivalent Cs1+ and two equivalent O2- atoms. Both H–O bond lengths are 1.23 Å. O2- is bonded in a trigonal planar geometry to three H1+ atoms.
