Materials Data on Cs2Si(HO2)2 by Materials Project
Cs2Si(HO2)2 crystallizes in the triclinic P-1 space group. The structure is three-dimensional. there are two inequivalent Cs1+ sites. In the first Cs1+ site, Cs1+ is bonded in a 2-coordinate geometry to two H1+ and seven O2- atoms. There are one shorter (3.11 Å) and one longer (3.21 Å) Cs–H bond lengths. There are a spread of Cs–O bond distances ranging from 3.15–3.52 Å. In the second Cs1+ site, Cs1+ is bonded in a 5-coordinate geometry to five O2- atoms. There are a spread of Cs–O bond distances ranging from 2.98–3.17 Å. Si4+ is bonded in a tetrahedral geometry to four O2- atoms. There is two shorter (1.62 Å) and two longer (1.72 Å) Si–O bond length. There are two inequivalent H1+ sites. In the first H1+ site, H1+ is bonded in a single-bond geometry to one Cs1+ and one O2- atom. The H–O bond length is 0.99 Å. In the second H1+ site, H1+ is bonded in a single-bond geometry to one Cs1+ and one O2- atom. The H–O bond length is 1.01 Å. There are four inequivalent O2- sites. In the first O2- site, O2- is bonded in a distorted water-like geometry to three Cs1+, one Si4+, and one H1+ atom. In the second O2- site, O2- is bonded in a distorted water-like geometry to three Cs1+, one Si4+, and one H1+ atom. In the third O2- site, O2- is bonded in a distorted single-bond geometry to two equivalent Cs1+ and one Si4+ atom. In the fourth O2- site, O2- is bonded in a distorted single-bond geometry to four Cs1+ and one Si4+ atom.
