Materials Data on Sc2Se3O10 by Materials Project

Sc2Se3O10 crystallizes in the orthorhombic P2_12_12_1 space group. The structure is three-dimensional. there are two inequivalent Sc3+ sites. In the first Sc3+ site, Sc3+ is bonded to seven O2- atoms to form distorted edge-sharing ScO7 pentagonal bipyramids. There are a spread of Sc–O bond distances ranging from 2.09–2.60 Å. In the second Sc3+ site, Sc3+ is bonded to seven O2- atoms to form distorted edge-sharing ScO7 pentagonal bipyramids. There are a spread of Sc–O bond distances ranging from 2.06–2.34 Å. There are three inequivalent Se+4.67+ sites. In the first Se+4.67+ site, Se+4.67+ is bonded in a trigonal non-coplanar geometry to three O2- atoms. There are a spread of Se–O bond distances ranging from 1.69–1.76 Å. In the second Se+4.67+ site, Se+4.67+ is bonded in a trigonal non-coplanar geometry to three O2- atoms. There are a spread of Se–O bond distances ranging from 1.71–1.75 Å. In the third Se+4.67+ site, Se+4.67+ is bonded in a trigonal non-coplanar geometry to three O2- atoms. There are a spread of Se–O bond distances ranging from 1.71–1.73 Å. There are ten inequivalent O2- sites. In the first O2- site, O2- is bonded in a bent 120 degrees geometry to one Sc3+ and one Se+4.67+ atom. In the second O2- site, O2- is bonded in a distorted trigonal planar geometry to two Sc3+ and one Se+4.67+ atom. In the third O2- site, O2- is bonded in a 3-coordinate geometry to two Sc3+ and one Se+4.67+ atom. In the fourth O2- site, O2- is bonded in a bent 150 degrees geometry to one Sc3+ and one Se+4.67+ atom. In the fifth O2- site, O2- is bonded in a distorted bent 120 degrees geometry to one Sc3+ and one Se+4.67+ atom. In the sixth O2- site, O2- is bonded in a distorted bent 150 degrees geometry to two Sc3+ and one Se+4.67+ atom. In the seventh O2- site, O2- is bonded in a bent 150 degrees geometry to one Sc3+ and one Se+4.67+ atom. In the eighth O2- site, O2- is bonded in a distorted trigonal planar geometry to two Sc3+ and one Se+4.67+ atom. In the ninth O2- site, O2- is bonded in a single-bond geometry to one Sc3+ atom. In the tenth O2- site, O2- is bonded in a bent 150 degrees geometry to one Sc3+ and one Se+4.67+ atom.

Materials Data on Sc2Se3O10 by Materials Project

Sc2Se3O10 crystallizes in the monoclinic P2_1/c space group. The structure is three-dimensional. there are two inequivalent Sc3+ sites. In the first Sc3+ site, Sc3+ is bonded to seven O2- atoms to form ScO7 pentagonal bipyramids that share corners with two equivalent SeO4 tetrahedra and edges with two equivalent ScO7 pentagonal bipyramids. There are a spread of Sc–O bond distances ranging from 2.04–2.28 Å. In the second Sc3+ site, Sc3+ is bonded to seven O2- atoms to form distorted ScO7 pentagonal bipyramids that share corners with two equivalent SeO4 tetrahedra and edges with two equivalent ScO7 pentagonal bipyramids. There are a spread of Sc–O bond distances ranging from 2.11–2.63 Å. There are three inequivalent Se+4.67+ sites. In the first Se+4.67+ site, Se+4.67+ is bonded in a trigonal non-coplanar geometry to three O2- atoms. There are a spread of Se–O bond distances ranging from 1.69–1.76 Å. In the second Se+4.67+ site, Se+4.67+ is bonded in a trigonal non-coplanar geometry to three O2- atoms. There are a spread of Se–O bond distances ranging from 1.70–1.75 Å. In the third Se+4.67+ site, Se+4.67+ is bonded to four O2- atoms to form SeO4 tetrahedra that share corners with four ScO7 pentagonal bipyramids. There is three shorter (1.66 Å) and one longer (1.68 Å) Se–O bond length. There are ten inequivalent O2- sites.
