Materials Data on KB5(H2O3)4 by Materials Project
KB5H8O12 crystallizes in the orthorhombic Aea2 space group. The structure is two-dimensional and consists of two KB5H8O12 sheets oriented in the (0, 1, 0) direction. K1+ is bonded in a 8-coordinate geometry to eight O2- atoms. There are a spread of K–O bond distances ranging from 2.86–3.03 Å. There are three inequivalent B3+ sites. In the first 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. 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 (1.39 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. There are four inequivalent H1+ sites. In the first 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 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. There are six inequivalent O2- sites. In the first O2- site, O2- is bonded in a bent 120 degrees geometry to one K1+ and two B3+ atoms. In the second O2- site, O2- is bonded in a distorted water-like geometry to one B3+ and one H1+ atom. In the third O2- site, O2- is bonded in a distorted bent 120 degrees geometry to one K1+, one B3+, and one H1+ atom. In the fourth O2- site, O2- is bonded in a distorted water-like geometry to one K1+ and two H1+ atoms. In the fifth O2- site, O2- is bonded in a bent 120 degrees geometry to two B3+ atoms. In the sixth O2- site, O2- is bonded in a bent 120 degrees geometry to one K1+ and two B3+ atoms.
