title: Materials Data on CsB5(H2O3)4 by Materials Project

description: CsB5(H2O3)4 crystallizes in the monoclinic P2_1/c space group. The structure is one-dimensional and consists of four CsB5(H2O3)4 ribbons oriented in the (1, 0, 0) direction. Cs1+ is bonded in a 6-coordinate geometry to six O2- atoms. There are a spread of Cs–O bond distances ranging from 3.13–3.32 Å. There are five inequivalent B3+ sites. In the first B3+ site, B3+ is bonded in a trigonal planar geometry to three O2- atoms. There is two shorter (1.37 Å) and one longer (1.39 Å) B–O bond length. In the second B3+ site, B3+ is bonded in a trigonal planar geometry to three O2- atoms. There is two shorter (1.37 Å) and one longer (1.40 Å) B–O bond length. In the third B3+ site, B3+ is bonded in a trigonal planar geometry to three O2- atoms. There is two shorter (1.37 Å) and one longer (1.39 Å) B–O bond length. In the fourth B3+ site, B3+ is bonded in a trigonal planar geometry to three O2- atoms. There are a spread of B–O bond distances ranging from 1.36–1.39 Å. In the fifth B3+ site, B3+ is bonded in a tetrahedral geometry to four O2- atoms. There is two shorter (1.48 Å) and two longer (1.49 Å) B–O bond length. There are eight inequivalent H1+ sites. In the first H1+ site, H1+ is bonded in a single-bond geometry to 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 O2- atom. The H–O bond length is 0.99 Å. In the third H1+ site, H1+ is bonded in a single-bond geometry to one O2- atom. The H–O bond length is 0.99 Å. In the fourth H1+ site, H1+ is bonded in a single-bond geometry to one O2- atom. The H–O bond length is 0.99 Å. In the fifth H1+ site, H1+ is bonded in a distorted single-bond geometry to two O2- atoms. There is one shorter (1.01 Å) and one longer (1.64 Å) H–O bond length. In the sixth H1+ site, H1+ is bonded in a single-bond geometry to one O2- atom. The H–O bond length is 0.99 Å. In the seventh H1+ site, H1+ is bonded in a distorted single-bond geometry to one O2- atom. The H–O bond length is 1.01 Å. In the eighth H1+ site, H1+ is bonded in a single-bond geometry to one O2- atom. The H–O bond length is 0.99 Å. There are twelve inequivalent O2- sites. In the first O2- site, O2- is bonded in a distorted water-like geometry to one Cs1+ and two H1+ atoms. In the second O2- site, O2- is bonded in a distorted water-like geometry to one Cs1+ and three H1+ atoms. In the third O2- site, O2- is bonded in a distorted bent 120 degrees geometry to one B3+ and one H1+ atom. In the fourth O2- site, O2- is bonded in a bent 120 degrees geometry to one Cs1+, one B3+, and one H1+ atom. In the fifth O2- site, O2- is bonded in a distorted bent 120 degrees geometry to one B3+ and one H1+ atom. In the sixth O2- site, O2- is bonded in a bent 120 degrees geometry to one Cs1+, one B3+, and one H1+ atom. In the seventh O2- site, O2- is bonded in a bent 120 degrees geometry to one Cs1+ and two B3+ atoms. In the eighth O2- site, O2- is bonded in a bent 120 degrees geometry to one Cs1+ and two B3+ atoms. In the ninth O2- site, O2- is bonded in a bent 120 degrees geometry to two B3+ atoms. In the tenth O2- site, O2- is bonded in a bent 120 degrees geometry to two B3+ atoms. In the eleventh O2- site, O2- is bonded in a bent 120 degrees geometry to two B3+ atoms. In the twelfth O2- site, O2- is bonded in a bent 120 degrees geometry to two B3+ atoms.
