The structure described by Eu2SmSbO6 is Orthorhombic Perovskite-derived structured and crystallizes in the cubic Pn-3 space group. There are two inequivalent Eu sites. In the first Eu site, Eu(1) is bonded to twelve equivalent O(1) atoms to form EuO12 cuboctahedra that share faces with four equivalent Sm(1)O6 octahedra and faces with four equivalent Sb(1)O6 octahedra. In the second Eu site, Eu(2) is bonded in a distorted square co-planar geometry to eight equivalent O(1) atoms. Sm(1) is bonded to six equivalent O(1) atoms to form SmO6 octahedra that share corners with six equivalent Sb(1)O6 octahedra and faces with two equivalent Eu(1)O12 cuboctahedra. The corner-sharing octahedral tilt angles are 25°. Sb(1) is bonded to six equivalent O(1) atoms to form SbO6 octahedra that share corners with six equivalent Sm(1)O6 octahedra and faces with two equivalent Eu(1)O12 cuboctahedra. The corner-sharing octahedral tilt angles are 25°. O(1) is bonded in a 3-coordinate geometry to one Eu(1), two equivalent Eu(2), one Sm(1), and one Sb(1) atom. is represented by the Crystallographic Information File (CIF) [CIF]
