KTbPrNbO6 is (Cubic) Perovskite-derived structured and crystallizes in the cubic F-43m space group. K(1) is bonded to twelve equivalent O(1) atoms to form KO12 cuboctahedra that share corners with twelve equivalent K(1)O12 cuboctahedra, faces with six equivalent Pr(1)O12 cuboctahedra, faces with four equivalent Tb(1)O6 octahedra, and faces with four equivalent Nb(1)O6 octahedra. Tb(1) is bonded to six equivalent O(1) atoms to form TbO6 octahedra that share corners with six equivalent Nb(1)O6 octahedra, faces with four equivalent K(1)O12 cuboctahedra, and faces with four equivalent Pr(1)O12 cuboctahedra. The corner-sharing octahedra are not tilted. Pr(1) is bonded to twelve equivalent O(1) atoms to form PrO12 cuboctahedra that share corners with twelve equivalent Pr(1)O12 cuboctahedra, faces with six equivalent K(1)O12 cuboctahedra, faces with four equivalent Tb(1)O6 octahedra, and faces with four equivalent Nb(1)O6 octahedra. Nb(1) is bonded to six equivalent O(1) atoms to form NbO6 octahedra that share corners with six equivalent Tb(1)O6 octahedra, faces with four equivalent K(1)O12 cuboctahedra, and faces with four equivalent Pr(1)O12 cuboctahedra. The corner-sharing octahedra are not tilted. O(1) is bonded in a distorted linear geometry to two equivalent K(1), one Tb(1), two equivalent Pr(1), and one Nb(1) atom.
