Materials Data on Nd3VGeO9 by Materials Project
Abstract
Nd3VGeO9 crystallizes in the monoclinic P2_1/c space group. The structure is three-dimensional. there are three inequivalent Nd3+ sites. In the first Nd3+ site, Nd3+ is bonded in a 8-coordinate geometry to eight O2- atoms. There are a spread of Nd–O bond distances ranging from 2.43–2.67 Å. In the second Nd3+ site, Nd3+ is bonded in a 8-coordinate geometry to eight O2- atoms. There are a spread of Nd–O bond distances ranging from 2.37–2.81 Å. In the third Nd3+ site, Nd3+ is bonded to seven O2- atoms to form distorted NdO7 pentagonal bipyramids that share a cornercorner with one VO4 tetrahedra, corners with two equivalent GeO4 tetrahedra, an edgeedge with one NdO7 pentagonal bipyramid, and an edgeedge with one VO4 tetrahedra. There are a spread of Nd–O bond distances ranging from 2.34–2.61 Å. V5+ is bonded to four O2- atoms to form VO4 tetrahedra that share a cornercorner with one NdO7 pentagonal bipyramid and an edgeedge with one NdO7 pentagonal bipyramid. There are a spread of V–O bond distances ranging from 1.72–1.76 Å. Ge4+ is bonded to four O2- atoms to form GeO4 tetrahedra that share corners with two equivalent NdO7 pentagonal bipyramids. There are a spread of Ge–O bond distancesmore »
