The crystal structure described by SrLa3 is beta Cu3Ti-like structured and crystallizes in the tetragonal I4/mmm space group. Sr(1) is bonded to four equivalent La(2) and eight equivalent La(1) atoms to form SrLa12 cuboctahedra that share corners with four equivalent Sr(1)La12 cuboctahedra, corners with eight equivalent La(2)Sr4La8 cuboctahedra, edges with eight equivalent Sr(1)La12 cuboctahedra, edges with sixteen equivalent La(1)Sr4La8 cuboctahedra, faces with four equivalent Sr(1)La12 cuboctahedra, faces with six equivalent La(2)Sr4La8 cuboctahedra, and faces with eight equivalent La(1)Sr4La8 cuboctahedra. There are two inequivalent La sites. In the first La site, La(1) is bonded to four equivalent Sr(1), four equivalent La(1), and four equivalent La(2) atoms to form LaSr4La8 cuboctahedra that share corners with twelve equivalent La(1)Sr4La8 cuboctahedra, edges with eight equivalent Sr(1)La12 cuboctahedra, edges with eight equivalent La(1)Sr4La8 cuboctahedra, edges with eight equivalent La(2)Sr4La8 cuboctahedra, faces with four equivalent Sr(1)La12 cuboctahedra, faces with four equivalent La(2)Sr4La8 cuboctahedra, and faces with ten equivalent La(1)Sr4La8 cuboctahedra. In the second La site, La(2) is bonded to four equivalent Sr(1) and eight equivalent La(1) atoms to form LaSr4La8 cuboctahedra that share corners with four equivalent La(2)Sr4La8 cuboctahedra, corners with eight equivalent Sr(1)La12 cuboctahedra, edges with eight equivalent La(2)Sr4La8 cuboctahedra, edges with sixteen equivalent La(1)Sr4La8 cuboctahedra, faces with four equivalent La(2)Sr4La8 cuboctahedra, faces with six equivalent Sr(1)La12 cuboctahedra, and faces with eight equivalent La(1)Sr4La8 cuboctahedra. is represented by the Crystallographic Information File (CIF) [CIF]
