Materials Data on EuV(SeO4)2 by Materials Project

EuV(SeO4)2 crystallizes in the monoclinic P2_1/m space group. The structure is three-dimensional. there are two inequivalent Eu3+ sites. In the first Eu3+ site, Eu3+ is bonded in a 9-coordinate geometry to nine O2- atoms. There are a spread of Eu–O bond distances ranging from 2.35–2.73 Å. In the second Eu3+ site, Eu3+ is bonded in a 9-coordinate geometry to nine O2- atoms. There are a spread of Eu–O bond distances ranging from 2.35–2.74 Å. V5+ is bonded in a 6-coordinate geometry to six O2- atoms. There are a spread of V–O bond distances ranging from 1.66–2.46 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 (1.72 Å) and two longer (1.74 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 (1.69 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 (1.75 Å) Se–O bond length. There are eleven inequivalent O2- sites. In the first O2- site, O2- is bonded in a bent 150 degrees geometry to one Eu3+ and one Se4+ atom. In the second O2- site, O2- is bonded in a 2-coordinate geometry to three Eu3+ and one Se4+ atom. In the third O2- site, O2- is bonded in a 2-coordinate geometry to two Eu3+ and one Se4+ atom.
