Materials Data on GdYV2O8 by Materials Project

Abstract

GdYV2O8 is Zircon-derived structured and crystallizes in the tetragonal I-4m2 space group. The structure is three-dimensional. Gd3+ is bonded in a 8-coordinate geometry to eight O2- atoms. There are four shorter (2.35 Å) and four longer (2.48 Å) Gd–O bond lengths. Y3+ is bonded in a 8-coordinate geometry to eight O2- atoms. There are four shorter (2.34 Å) and four longer (2.45 Å) Y–O bond lengths. There are two inequivalent V5+ sites. In the first V5+ site, V5+ is bonded in a tetrahedral geometry to four equivalent O2- atoms. All V–O bond lengths are 1.74 Å. In the second V5+ site, V5+ is bonded in a tetrahedral geometry to four equivalent O2- atoms. All V–O bond lengths are 1.74 Å. There are two inequivalent O2- sites. In the first O2- site, O2- is bonded in a 1-coordinate geometry to one Gd3+, one Y3+, and one V5+ atom. In the second O2- site, O2- is bonded in a 1-coordinate geometry to one Gd3+, one Y3+, and one V5+ atom.
