Eu2NbWO6 is (Cubic) Perovskite-derived structured and crystallizes in the cubic Fm-3m space group. 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 Eu(1)O12 cuboctahedra, faces with four equivalent Nb(1)O6 octahedra, and faces with four equivalent W(1)O6 octahedra. Nb(1) is bonded to six equivalent O(1) atoms to form NbO6 octahedra that share corners with six equivalent W(1)O6 octahedra and faces with eight equivalent Eu(1)O12 cuboctahedra. The corner-sharing octahedra are not tilted. W(1) is bonded to six equivalent O(1) atoms to form WO6 octahedra that share corners with six equivalent Nb(1)O6 octahedra and faces with eight equivalent Eu(1)O12 cuboctahedra. The corner-sharing octahedra are not tilted. O(1) is bonded to four equivalent Eu(1), one Nb(1), and one W(1) atom to form a mixture of distorted corner, edge, and face-sharing OEu4NbW octahedra. The corner-sharing octahedral tilt angles range from 0-60°.
