Materials Data on TbPrO4 by Materials Project

Abstract

TbPrO4 is alpha bismuth trifluoride-derived structured and crystallizes in the monoclinic P2_1/c space group. The structure is three-dimensional. Tb4+ is bonded in a body-centered cubic geometry to eight O2- atoms. There are a spread of Tb–O bond distances ranging from 2.32–2.43 Å. Pr4+ is bonded in a body-centered cubic geometry to eight O2- atoms. There are a spread of Pr–O bond distances ranging from 2.44–2.60 Å. There are four inequivalent O2- sites. In the first O2- site, O2- is bonded to one Tb4+ and three equivalent Pr4+ atoms to form a mixture of edge and corner-sharing OTbPr3 tetrahedra. In the second O2- site, O2- is bonded to one Tb4+ and three equivalent Pr4+ atoms to form a mixture of edge and corner-sharing OTbPr3 tetrahedra. In the third O2- site, O2- is bonded to three equivalent Tb4+ and one Pr4+ atom to form a mixture of distorted edge and corner-sharing OTb3Pr tetrahedra. In the fourth O2- site, O2- is bonded to three equivalent Tb4+ and one Pr4+ atom to form a mixture of distorted edge and corner-sharing OTb3Pr tetrahedra.
