Sr2NbBiO6 is (Cubic) Perovskite-derived structured and crystallizes in the cubic Fm-3m 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 Sr(1)O12 cuboctahedra, faces with four equivalent Nb(1)O6 octahedra, and faces with four equivalent Bi(1)O6 octahedra. Nb(1) is bonded to six equivalent O(1) atoms to form NbO6 octahedra that share corners with six equivalent Bi(1)O6 octahedra and faces with eight equivalent Sr(1)O12 cuboctahedra. The corner-sharing octahedra are not tilted. Bi(1) is bonded to six equivalent O(1) atoms to form BiO6 octahedra that share corners with six equivalent Nb(1)O6 octahedra and faces with eight equivalent Sr(1)O12 cuboctahedra. The corner-sharing octahedra are not tilted. O(1) is bonded to four equivalent Sr(1), one Nb(1), and one Bi(1) atom to form a mixture of distorted face, corner, and edge-sharing OSr4NbBi octahedra. The corner-sharing octahedral tilt angles range from 0-60°.
