EuNbGaSnO6 crystallizes in the cubic F-43m 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 Sn(1)O12 cuboctahedra, faces with four equivalent Nb(1)O6 octahedra, and faces with four equivalent Ga(1)O6 octahedra. Nb(1) is bonded to six equivalent O(1) atoms to form NbO6 octahedra that share corners with six equivalent Ga(1)O6 octahedra, faces with four equivalent Eu(1)O12 cuboctahedra, and faces with four equivalent Sn(1)O12 cuboctahedra. The corner-sharing octahedra are not tilted. Ga(1) is bonded to six equivalent O(1) atoms to form GaO6 octahedra that share corners with six equivalent Nb(1)O6 octahedra, faces with four equivalent Eu(1)O12 cuboctahedra, and faces with four equivalent Sn(1)O12 cuboctahedra. The corner-sharing octahedra are not tilted. Sn(1) is bonded to twelve equivalent O(1) atoms to form distorted SnO12 cuboctahedra that share corners with twelve equivalent Sn(1)O12 cuboctahedra, faces with six equivalent Eu(1)O12 cuboctahedra, faces with four equivalent Nb(1)O6 octahedra, and faces with four equivalent Ga(1)O6 octahedra. O(1) is bonded in a distorted linear geometry to two equivalent Eu(1), one Nb(1), one Ga(1), and two equivalent Sn(1) atoms.
