Materials Data on CsH3O2 by Materials Project

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.

Materials Data on CsHO by Materials Project

CsOH crystallizes in the orthorhombic Cmc2_1 space group. The structure is three-dimensional. Cs1+ is bonded in a 9-coordinate geometry to four equivalent H1+ and five equivalent O2- atoms. There are two shorter (3.03 Å) and two longer (3.25 Å) Cs–H bond lengths. There are a spread of Cs–O bond distances ranging from 3.00–3.25 Å. H1+ is bonded in a single-bond geometry to four equivalent Cs1+ and one O2- atom. The H–O bond length is 0.98 Å. O2- is bonded in a single-bond geometry to five equivalent Cs1+ and one H1+ atom.

There are a spread of Cs–H bond distances ranging from 3.17–3.23 Å. There are two inequivalent H1+ sites. In the first H1+ site, H1+ is bonded in a single-bond geometry to four equivalent Cs1+ and one O2- atom. The H–O bond length is 0.99 Å. In the second H1+ site, H1+ is bonded in a linear geometry to four equivalent Cs1+ and two O2- atoms. There is one shorter (1.04 Å) and one longer (1.53 Å) H–O bond length. There are two inequivalent O2- sites. In the first O2- site, O2- is bonded in a trigonal planar geometry to three H1+ atoms. In the second O2- site, O2- is bonded in a water-like geometry to two equivalent H1+ atoms.
