Title: Materials Data on Eu3VGeO9 by Materials Project

Abstract

Eu3VGeO9 crystallizes in the monoclinic P2_1/c space group. The structure is three-dimensional. there are three inequivalent Eu3+ sites. In the first Eu3+ site, Eu3+ is bonded in a 8-coordinate geometry to eight O2- atoms. There are a spread of Eu–O bond distances ranging from 2.39–2.70 Å. In the second Eu3+ site, Eu3+ is bonded in a 8-coordinate geometry to eight O2- atoms. There are a spread of Eu–O bond distances ranging from 2.35–2.84 Å. In the third Eu3+ site, Eu3+ is bonded to seven O2- atoms to form distorted EuO7 pentagonal bipyramids that share a cornercorner with one VO4 tetrahedra, corners with two equivalent GeO4 tetrahedra, an edgeedge with one EuO7 pentagonal bipyramid, and an edgeedge with one VO4 tetrahedra. There are a spread of Eu–O bond distances ranging from 2.31–2.66 Å. V5+ is bonded to four O2- atoms to form VO4 tetrahedra that share a cornercorner with one EuO7 pentagonal bipyramid and an edgeedge with one EuO7 pentagonal bipyramid. There is one shorter (1.73 Å) and three longer (1.74 Å) V–O bond length. Ge4+ is bonded to four O2- atoms to form GeO4 tetrahedra that share corners with two equivalent EuO7 pentagonal bipyramids. There are a spread of Ge–Omore » bond distances ranging from 1.75–1.82 Å. There are nine inequivalent O2- sites. In the first O2- site, O2- is bonded in a 3-coordinate geometry to two Eu3+ and one Ge4+ atom. In the second O2- site, O2- is bonded in a 1-coordinate geometry to three Eu3+ and one V5+ atom. In the third O2- site, O2- is bonded to four Eu3+ atoms to form edge-sharing OEu4 tetrahedra. In the fourth O2- site, O2- is bonded in a 4-coordinate geometry to three Eu3+ and one Ge4+ atom. In the fifth O2- site, O2- is bonded in a 1-coordinate geometry to two Eu3+ and one V5+ atom. In the sixth O2- site, O2- is bonded in a 3-coordinate geometry to two Eu3+ and one V5+ atom. In the seventh O2- site, O2- is bonded in a 1-coordinate geometry to two Eu3+ and one Ge4+ atom. In the eighth O2- site, O2- is bonded in a 4-coordinate geometry to three Eu3+ and one Ge4+ atom. In the ninth O2- site, O2- is bonded in a 1-coordinate geometry to two Eu3+ and one V5+ atom.« less
