Materials Data on CsH(CO2)2 by Materials Project
CsH(CO2)2 crystallizes in the monoclinic P2_1/c space group. The structure is three-dimensional. Cs1+ is bonded in a 7-coordinate geometry to two equivalent H1+ and nine O2- atoms. There are one shorter (3.23 Å) and one longer (3.27 Å) Cs–H bond lengths. There are a spread of Cs–O bond distances ranging from 3.08–3.74 Å. There are two inequivalent C3+ sites. In the first C3+ site, C3+ is bonded in a bent 120 degrees geometry to two O2- atoms. There is one shorter (1.25 Å) and one longer (1.29 Å) C–O bond length. In the second C3+ site, C3+ is bonded in a bent 120 degrees geometry to two O2- atoms. There is one shorter (1.24 Å) and one longer (1.30 Å) C–O bond length. H1+ is bonded in a bent 150 degrees geometry to two equivalent Cs1+ and two O2- atoms. There is one shorter (1.13 Å) and one longer (1.32 Å) H–O bond length. There are four inequivalent O2- sites. In the first O2- site, O2- is bonded in a 2-coordinate geometry to two equivalent Cs1+, one C3+, and one H1+ atom. In the second O2- site, O2- is bonded in a distorted single-bond geometry to three equivalent Cs1+ and one C3+ atom. In the third O2- site, O2- is bonded in a distorted bent 120 degrees geometry to two equivalent Cs1+, one C3+, and one H1+ atom. In the fourth O2- site, O2- is bonded in a distorted single-bond geometry to two equivalent Cs1+ and one C3+ atom.
