Materials Data on B3H3SeO9 by Materials Project
B3H3SeO9 crystallizes in the orthorhombic Pbcn space group. The structure is one-dimensional and consists of four B3H3SeO9 ribbons oriented in the (1, 0, 0) direction. there are three inequivalent B3+ sites. In the first 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 1.34–1.42 Å. In the second 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 1.35–1.41 Å. In the third B3+ site, B3+ is bonded to four O2- atoms to form BO4 tetrahedra that share corners with two equivalent SeO4 tetrahedra. There are a spread of B–O bond distances ranging from 1.43–1.56 Å. There are three 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 0.98 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 1.02 Å. Se6+ is bonded to four O2- atoms to form SeO4 tetrahedra that share corners with two equivalent BO4 tetrahedra. There are a spread of Se–O bond distances ranging from 1.60–1.74 Å. There are nine inequivalent O2- sites. In the first O2- site, O2- is bonded in a bent 120 degrees geometry to two B3+ atoms. In the second O2- site, O2- is bonded in a bent 120 degrees geometry to one B3+ and one H1+ atom. In the third O2- site, O2- is bonded in a bent 120 degrees geometry to one B3+ and one H1+ atom. In the fourth O2- site, O2- is bonded in a distorted water-like geometry to one H1+ and one Se6+ atom. In the fifth O2- site, O2- is bonded in a bent 120 degrees geometry to one B3+ and one Se6+ atom. In the sixth O2- site, O2- is bonded in a bent 120 degrees geometry to one B3+ and one Se6+ atom. In the seventh O2- site, O2- is bonded in a bent 120 degrees geometry to two B3+ atoms. In the eighth O2- site, O2- is bonded in a single-bond geometry to one Se6+ atom. In the ninth O2- site, O2- is bonded in a bent 120 degrees geometry to two B3+ atoms.
