Materials Data on Sr4V2(Se2O7)3 by Materials Project
Abstract
Sr4V2(Se2O7)3 crystallizes in the orthorhombic Fdd2 space group. The structure is three-dimensional. there are two inequivalent Sr2+ sites. In the first Sr2+ site, Sr2+ is bonded in a 7-coordinate geometry to seven O2- atoms. There are a spread of Sr–O bond distances ranging from 2.56–2.83 Å. In the second Sr2+ site, Sr2+ is bonded in a 7-coordinate geometry to nine O2- atoms. There are a spread of Sr–O bond distances ranging from 2.49–3.19 Å. V5+ is bonded in a distorted trigonal bipyramidal geometry to five O2- atoms. There are a spread of V–O bond distances ranging from 1.67–2.04 Å. There are three inequivalent Se4+ sites. In the first Se4+ site, Se4+ is bonded in a distorted trigonal non-coplanar geometry to three O2- atoms. There are a spread of Se–O bond distances ranging from 1.69–1.77 Å. In the second Se4+ site, Se4+ is bonded in a trigonal non-coplanar geometry to three O2- atoms. There is two shorter (1.73 Å) and one 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 are a spread of Se–O bond distances ranging from 1.70–1.86 Å. There are eleven inequivalent O2-more »
