Materials Data on YLuCr2O8 by Materials Project
LuYCr2O8 is Zircon-derived structured and crystallizes in the tetragonal I-4m2 space group. The structure is three-dimensional. Lu3+ is bonded in a 8-coordinate geometry to eight O2- atoms. There are four shorter (2.29 Å) and four longer (2.40 Å) Lu–O bond lengths. 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 two 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. There are two 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 one Lu3+, one Y3+, and one Cr5+ atom.
