The crystal structure described by TbPrO4 is Fluorite-derived structured and crystallizes in the monoclinic P2_1/c space group. Tb(1) is bonded in a body-centered cubic geometry to one O(1), one O(2), three equivalent O(3), and three equivalent O(4) atoms. Pr(1) is bonded in a body-centered cubic geometry to one O(3), one O(4), three equivalent O(1), and three equivalent O(2) atoms. There are four 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 four equivalent O(3)Tb3Pr tetrahedra, corners with four equivalent O(4)Tb3Pr tetrahedra, corners with four equivalent O(1)TbPr3 tetrahedra, corners with four equivalent O(2)TbPr3 tetrahedra,  an edgeedge with one O(3)Tb3Pr tetrahedra,  an edgeedge with one O(4)Tb3Pr tetrahedra,  an edgeedge with one O(1)TbPr3 tetrahedra, and edges with three equivalent O(2)TbPr3 tetrahedra. In the second O site, O(2) is bonded to one Tb(1) and three equivalent Pr(1) atoms to form OTbPr3 tetrahedra that share corners with four equivalent O(3)Tb3Pr tetrahedra, corners with four equivalent O(4)Tb3Pr tetrahedra, corners with four equivalent O(1)TbPr3 tetrahedra, corners with four equivalent O(2)TbPr3 tetrahedra,  an edgeedge with one O(3)Tb3Pr tetrahedra,  an edgeedge with one O(4)Tb3Pr tetrahedra,  an edgeedge with one O(2)TbPr3 tetrahedra, and edges with three equivalent O(1)TbPr3 tetrahedra. In the third O site, O(3) is bonded to three equivalent Tb(1) and one Pr(1) atom to form OTb3Pr tetrahedra that share corners with four equivalent O(3)Tb3Pr tetrahedra, corners with four equivalent O(4)Tb3Pr tetrahedra, corners with four equivalent O(1)TbPr3 tetrahedra, corners with four equivalent O(2)TbPr3 tetrahedra,  an edgeedge with one O(3)Tb3Pr tetrahedra,  an edgeedge with one O(1)TbPr3 tetrahedra,  an edgeedge with one O(2)TbPr3 tetrahedra, and edges with three equivalent O(4)Tb3Pr tetrahedra.
