SrEuNdNbO6 is (Cubic) Perovskite-derived structured and crystallizes in the cubic F-43m space group. Sr(1) is bonded to twelve equivalent O(1) atoms to form SrO12 cuboctahedra that share corners with twelve equivalent Sr(1)O12 cuboctahedra, faces with six equivalent Eu(1)O12 cuboctahedra, faces with four equivalent Nd(1)O6 octahedra, and faces with four equivalent Nb(1)O6 octahedra. Eu(1) is bonded to twelve equivalent O(1) atoms to form EuO12 cuboctahedra that share corners with twelve equivalent Eu(1)O12 cuboctahedra, faces with six equivalent Sr(1)O12 cuboctahedra, faces with four equivalent Nd(1)O6 octahedra, and faces with four equivalent Nb(1)O6 octahedra. Nd(1) is bonded to six equivalent O(1) atoms to form NdO6 octahedra that share corners with six equivalent Nb(1)O6 octahedra, faces with four equivalent Sr(1)O12 cuboctahedra, and faces with four equivalent Eu(1)O12 cuboctahedra. The corner-sharing octahedra are not tilted. Nb(1) is bonded to six equivalent O(1) atoms to form NbO6 octahedra that share corners with six equivalent Nd(1)O6 octahedra, faces with four equivalent Sr(1)O12 cuboctahedra, and faces with four equivalent Eu(1)O12 cuboctahedra. The corner-sharing octahedra are not tilted. O(1) is bonded in a distorted linear geometry to two equivalent Sr(1), two equivalent Eu(1), one Nd(1), and one Nb(1) atom.
