Materials Data on YLu3Cr4O16 by Materials Project

Abstract

Lu3YCr4O16 is Zircon-derived structured and crystallizes in the orthorhombic C222 space group. The structure is three-dimensional. there are two inequivalent Lu3+ sites. In the first Lu3+ site, Lu3+ is bonded in a 8-coordinate geometry to eight O2- atoms. There are four shorter (2.26 Å) and four longer (2.41 Å) Lu–O bond lengths. In the second Lu3+ site, Lu3+ is bonded in a 8-coordinate geometry to eight O2- atoms. There are a spread of Lu–O bond distances ranging from 2.27–2.41 Å. Y3+ is bonded in a 8-coordinate geometry to eight O2- atoms. There are four shorter (2.31 Å) and four longer (2.44 Å) Y–O bond lengths. There are three inequivalent Cr5+ sites. In the first Cr5+ site, Cr5+ is bonded in a tetrahedral geometry to four equivalent O2- atoms. All Cr–O bond lengths are 1.72 Å. In the second Cr5+ site, Cr5+ is bonded in a tetrahedral geometry to four equivalent O2- atoms. All Cr–O bond lengths are 1.73 Å. In the third Cr5+ site, Cr5+ is bonded in a tetrahedral geometry to four O2- atoms. All Cr–O bond lengths are 1.72 Å. There are four inequivalent O2- sites. In the first O2- site, O2- is bonded in a 1-coordinate geometry to one Lu3+, one Y3+, and one Cr5+ atom. In the second O2- site, O2- is bonded in a 1-coordinate geometry to two Lu3+ and one Cr5+ atom. In the third O2- site, O2- is bonded in a 1-coordinate geometry to one Lu3+, one Y3+, and one Cr5+ atom. In the fourth O2- site, O2- is bonded in a 1-coordinate geometry to two Lu3+ and one Cr5+ atom.
