Materials Data on KB3(H3O4)2 by Materials Project
(KB3H5O7)2H2O2 crystallizes in the monoclinic C2/c space group. The structure is three-dimensional and consists of eight water molecules and one KB3H5O7 framework. In the KB3H5O7 framework, there are two inequivalent K1+ sites. In the first K1+ site, K1+ is bonded in a 2-coordinate geometry to two equivalent H1+ and six O2- atoms. Both K–H bond lengths are 3.08 Å. There are a spread of K–O bond distances ranging from 2.69–3.22 Å. In the second K1+ site, K1+ is bonded in a 2-coordinate geometry to six O2- atoms. There are a spread of K–O bond distances ranging from 2.65–3.10 Å. There are three inequivalent B3+ sites. In the first B3+ site, B3+ is bonded in a linear geometry to two O2- atoms. There is one shorter (1.25 Å) and one longer (1.28 Å) B–O bond length. In the second B3+ site, B3+ is bonded in a trigonal planar geometry to three O2- atoms. There is one shorter (1.29 Å) and two longer (1.44 Å) B–O bond length. In the third B3+ site, B3+ is bonded in a linear geometry to two O2- atoms. There is one shorter (1.24 Å) and one longer (1.29 Å) B–O bond length. There are five inequivalent H1+ sites. In the first H1+ site, H1+ is bonded in a linear geometry to two O2- atoms. There is one shorter (1.17 Å) and one longer (1.25 Å) H–O bond length. In the second H1+ site, H1+ is bonded in a distorted linear geometry to two O2- atoms. There is one shorter (1.02 Å) and one longer (1.54 Å) H–O bond length. In the third H1+ site, H1+ is bonded in a single-bond geometry to one H1+ atom. The H–H bond length is 0.75 Å. In the fourth H1+ site, H1+ is bonded in a single-bond geometry to one O2- atom. The H–O bond length is 0.98 Å. In the fifth H1+ site, H1+ is bonded in a single-bond geometry to one K1+ and one H1+ atom. There are seven inequivalent O2- sites. In the first O2- site, O2- is bonded in a bent 150 degrees geometry to one K1+ and two B3+ atoms. In the second O2- site, O2- is bonded in a trigonal non-coplanar geometry to one K1+ 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 distorted single-bond geometry to one K1+ and one B3+ atom. In the fifth O2- site, O2- is bonded in a 3-coordinate geometry to one K1+, one B3+, and one H1+ atom. In the sixth O2- site, O2- is bonded in a single-bond geometry to one B3+ atom. In the seventh O2- site, O2- is bonded in a distorted single-bond geometry to two K1+ and one B3+ atom.
