SrDyEuSbO6 is Orthorhombic Perovskite-derived structured and crystallizes in the orthorhombic Pnnn space group. There are two inequivalent Sr sites. In the first Sr site, Sr(1) is bonded in a 8-coordinate geometry to four equivalent O(1) and four equivalent O(2) atoms. In the second Sr site, Sr(2) is bonded in a 8-coordinate geometry to four equivalent O(1) and four equivalent O(3) atoms. Dy(1) is bonded to two equivalent O(1), two equivalent O(2), and two equivalent O(3) atoms to form DyO6 octahedra that share corners with six equivalent Sb(1)O6 octahedra and faces with two equivalent Eu(2)O12 cuboctahedra.
