TbPrO4 is Fluorite-derived structured and crystallizes in the monoclinic P2_1/m space group. Tb(1) is bonded in a body-centered cubic geometry to two equivalent O(1) and six equivalent O(2) atoms. Pr(1) is bonded in a body-centered cubic geometry to two equivalent O(2) and six equivalent O(1) atoms. There are two inequivalent O sites. In the first O site, O(1) is bonded to one Tb(1) and three equivalent Pr(1) atoms to form OTbPr3 tetrahedra that share corners with eight equivalent O(2)Tb3Pr tetrahedra, corners with eight equivalent O(1)TbPr3 tetrahedra, edges with two equivalent O(2)Tb3Pr tetrahedra, and edges with four equivalent O(1)TbPr3 tetrahedra. In the second O site, O(2) is bonded to three equivalent Tb(1) and one Pr(1) atom to form OTb3Pr tetrahedra that share corners with eight equivalent O(2)Tb3Pr tetrahedra, corners with eight equivalent O(1)TbPr3 tetrahedra, edges with two equivalent O(1)TbPr3 tetrahedra, and edges with four equivalent O(2)Tb3Pr tetrahedra.
TbPrO4 is Fluorite-derived structured and crystallizes in the monoclinic P2_1/m space group. Tb(1) is bonded in a body-centered cubic geometry to two equivalent O(1) and six equivalent O(2) atoms. Both Tb(1)-O(1) bond lengths are 2.30 Å. There are a spread of Tb(1)-O(2) bond distances ranging from 2.39-2.42 Å. Pr(1) is bonded in a body-centered cubic geometry to two equivalent O(2) and six equivalent O(1) atoms. Both Pr(1)-O(2) bond lengths are 2.58 Å. There are four shorter (2.46 Å) and two longer (2.47 Å) Pr(1)-O(1) bond lengths. There are two inequivalent O sites. In the first O site, O(1) is bonded to one Tb(1) and three equivalent Pr(1) atoms to form OTbPr3 tetrahedra that share corners with eight equivalent O(2)Tb3Pr tetrahedra, corners with eight equivalent O(1)TbPr3 tetrahedra, edges with two equivalent O(2)Tb3Pr tetrahedra, and edges with four equivalent O(1)TbPr3 tetrahedra. In the second O site, O(2) is bonded to three equivalent Tb(1) and one Pr(1) atom to form OTb3Pr tetrahedra that share corners with eight equivalent O(2)Tb3Pr tetrahedra, corners with eight equivalent O(1)TbPr3 tetrahedra, edges with two equivalent O(1)TbPr3 tetrahedra, and edges with four equivalent O(2)Tb3Pr tetrahedra.
