Eu2YNbO6 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 Y(1)O6 octahedra, and faces with four equivalent Nb(1)O6 octahedra. Y(1) is bonded to six equivalent O(1) atoms to form YO6 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. Nb(1) is bonded to six equivalent O(1) atoms to form NbO6 octahedra that share corners with six equivalent Y(1)O6 octahedra and faces with eight equivalent Eu(1)O12 cuboctahedra. The corner-sharing octahedra are not tilted. O(1) is bonded in a distorted linear geometry to four equivalent Eu(1), one Y(1), and one Nb(1) atom.
