NaPrNb2O6 is (Cubic) Perovskite-derived structured and crystallizes in the cubic Fm-3m space group. Na(1) is bonded to twelve equivalent O(1) atoms to form NaO12 cuboctahedra that share corners with twelve equivalent Na(1)O12 cuboctahedra, faces with six equivalent Pr(1)O12 cuboctahedra, and faces with eight equivalent Nb(1)O6 octahedra. 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 Na(1)O12 cuboctahedra, and faces with eight 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 Nb(1)O6 octahedra, faces with four equivalent Na(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 Na(1), two equivalent Pr(1), and two equivalent Nb(1) atoms.
