The material structure described by SrDy3 is beta Cu3Ti-like structured and crystallizes in the tetragonal I4/mmm space group. Sr(1) is bonded to four equivalent Dy(2) and eight equivalent Dy(1) atoms to form SrDy12 cuboctahedra that share corners with four equivalent Sr(1)Dy12 cuboctahedra, corners with eight equivalent Dy(2)Sr4Dy8 cuboctahedra, edges with eight equivalent Sr(1)Dy12 cuboctahedra, edges with sixteen equivalent Dy(1)Sr4Dy8 cuboctahedra, faces with four equivalent Sr(1)Dy12 cuboctahedra, faces with six equivalent Dy(2)Sr4Dy8 cuboctahedra, and faces with eight equivalent Dy(1)Sr4Dy8 cuboctahedra. There are two inequivalent Dy sites. In the first Dy site, Dy(1) is bonded to four equivalent Sr(1), four equivalent Dy(1), and four equivalent Dy(2) atoms to form DySr4Dy8 cuboctahedra that share corners with twelve equivalent Dy(1)Sr4Dy8 cuboctahedra, edges with eight equivalent Sr(1)Dy12 cuboctahedra, edges with eight equivalent Dy(1)Sr4Dy8 cuboctahedra, edges with eight equivalent Dy(2)Sr4Dy8 cuboctahedra, faces with four equivalent Sr(1)Dy12 cuboctahedra, faces with four equivalent Dy(2)Sr4Dy8 cuboctahedra, and faces with ten equivalent Dy(1)Sr4Dy8 cuboctahedra. In the second Dy site, Dy(2) is bonded to four equivalent Sr(1) and eight equivalent Dy(1) atoms to form DySr4Dy8 cuboctahedra that share corners with four equivalent Dy(2)Sr4Dy8 cuboctahedra, corners with eight equivalent Sr(1)Dy12 cuboctahedra, edges with eight equivalent Dy(2)Sr4Dy8 cuboctahedra, edges with sixteen equivalent Dy(1)Sr4Dy8 cuboctahedra, faces with four equivalent Dy(2)Sr4Dy8 cuboctahedra, faces with six equivalent Sr(1)Dy12 cuboctahedra, and faces with eight equivalent Dy(1)Sr4Dy8 cuboctahedra. is represented by the Crystallographic Information File (CIF) [CIF]
