Materials Data on TbV(SeO4)2 by Materials Project

Abstract

TbV(SeO4)2 crystallizes in the monoclinic P2_1/m space group. The structure is three-dimensional. there are two inequivalent Tb3+ sites. In the first Tb3+ site, Tb3+ is bonded in a 9-coordinate geometry to nine O2- atoms. There are a spread of Tb–O bond distances ranging from 2.29–2.70 Å. In the second Tb3+ site, Tb3+ is bonded in a 9-coordinate geometry to nine O2- atoms. There are a spread of Tb–O bond distances ranging from 2.28–2.64 Å. V5+ is bonded in a 6-coordinate geometry to six O2- atoms. There are a spread of V–O bond distances ranging from 1.67–2.45 Å. There are four inequivalent Se4+ sites. In the first Se4+ site, Se4+ is bonded in a trigonal non-coplanar geometry to three O2- atoms. There is one shorter (1.69 Å) and two longer (1.76 Å) Se–O bond length. In the second Se4+ site, Se4+ is bonded in a trigonal non-coplanar geometry to three O2- atoms. There is one shorter (1.74 Å) and two longer (1.75 Å) Se–O bond length. In the third Se4+ site, Se4+ is bonded in a trigonal non-coplanar geometry to three O2- atoms. There is one shorter (1.70 Å) and two longer (1.78 Å) Se–O bond length. In the fourth Se4+ site, Se4+ is bonded in a distorted T-shaped geometry to three O2- atoms. There is one shorter (1.72 Å) and two longer (1.76 Å) Se–O bond length. There are eleven inequivalent O2- sites. In the first O2- site, O2- is bonded in a 2-coordinate geometry to two Tb3+ and one Se4+ atom. In the second O2- site, O2- is bonded in a 2-coordinate geometry to three Tb3+ and one Se4+ atom. In the third O2- site, O2- is bonded in a single-bond geometry to one Tb3+ and one V5+ atom. In the fourth O2- site, O2- is bonded in a distorted bent 120 degrees geometry to two equivalent V5+ atoms. In the fifth O2- site, O2- is bonded in a bent 150 degrees geometry to two equivalent V5+ atoms. In the sixth O2- site, O2- is bonded in a bent 150 degrees geometry to one Tb3+ and one Se4+ atom. In the seventh O2- site, O2- is bonded in a bent 120 degrees geometry to one V5+ and one Se4+ atom. In the eighth O2- site, O2- is bonded in a distorted trigonal planar geometry to two Tb3+ and one Se4+ atom. In the ninth O2- site, O2- is bonded in a distorted trigonal planar geometry to two Tb3+ and one Se4+ atom. In the tenth O2- site, O2- is bonded in a bent 150 degrees geometry to one Tb3+ and one Se4+ atom. In the eleventh O2- site, O2- is bonded in a 3-coordinate geometry to two equivalent V5+ and one Se4+ atom.
