TbZr4O10 is Fluorite-derived structured and crystallizes in the tetragonal I4/m space group. Tb(1) is bonded in a body-centered cubic geometry to eight equivalent O(1) atoms. Zr(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 Zr(1) atoms to form OTbZr3 tetrahedra that share corners with four equivalent O(2)Zr4 tetrahedra, corners with twelve equivalent O(1)TbZr3 tetrahedra,  an edgeedge with one O(2)Zr4 tetrahedra, and edges with five equivalent O(1)TbZr3 tetrahedra. In the second O site, O(2) is bonded to four equivalent Zr(1) atoms to form OZr4 tetrahedra that share corners with sixteen equivalent O(1)TbZr3 tetrahedra, edges with two equivalent O(2)Zr4 tetrahedra, and edges with four equivalent O(1)TbZr3 tetrahedra.
TbZr4O10 is Fluorite-derived structured and crystallizes in the tetragonal I4/m space group. Tb(1) is bonded in a body-centered cubic geometry to eight equivalent O(1) atoms. All Tb(1)-O(1) bond lengths are 2.33 Å. Zr(1) is bonded in a body-centered cubic geometry to two equivalent O(2) and six equivalent O(1) atoms. Both Zr(1)-O(2) bond lengths are 2.26 Å. There are a spread of Zr(1)-O(1) bond distances ranging from 2.22-2.24 Å. There are two inequivalent O sites. In the first O site, O(1) is bonded to one Tb(1) and three equivalent Zr(1) atoms to form OTbZr3 tetrahedra that share corners with four equivalent O(2)Zr4 tetrahedra, corners with twelve equivalent O(1)TbZr3 tetrahedra,  an edgeedge with one O(2)Zr4 tetrahedra, and edges with five equivalent O(1)TbZr3 tetrahedra.
