Materials Data on PrHfO4 by Materials Project

Abstract

PrHfO4 crystallizes in the tetragonal I4_1/a space group. The structure is three-dimensional. there are four inequivalent Pr4+ sites. In the first Pr4+ site, Pr4+ is bonded in a body-centered cubic geometry to eight equivalent O2- atoms. There are four shorter (2.45 Å) and four longer (2.50 Å) Pr–O bond lengths. In the second Pr4+ site, Pr4+ is bonded in a body-centered cubic geometry to eight equivalent O2- atoms. There are four shorter (2.45 Å) and four longer (2.50 Å) Pr–O bond lengths. In the third Pr4+ site, Pr4+ is bonded in a body-centered cubic geometry to eight equivalent O2- atoms. There are four shorter (2.45 Å) and four longer (2.50 Å) Pr–O bond lengths. In the fourth Pr4+ site, Pr4+ is bonded in a body-centered cubic geometry to eight equivalent O2- atoms. There are four shorter (2.45 Å) and four longer (2.50 Å) Pr–O bond lengths. There are four inequivalent Hf4+ sites. In the first Hf4+ site, Hf4+ is bonded in a distorted tetrahedral geometry to four equivalent O2- atoms. All Hf–O bond lengths are 2.01 Å. In the second Hf4+ site, Hf4+ is bonded in a distorted tetrahedral geometry to four equivalent O2- atoms. All Hf–O bond lengths are 2.01 Å. In the third Hf4+ site, Hf4+ is bonded in a distorted tetrahedral geometry to four equivalent O2- atoms. All Hf–O bond lengths are 2.01 Å. In the fourth Hf4+ site, Hf4+ is bonded in a distorted tetrahedral geometry to four equivalent O2- atoms. All Hf–O bond lengths are 2.01 Å. O2- is bonded in a 1-coordinate geometry to two Pr4+ and one Hf4+ atom.
