The crystal structure described by CeLaSn6 is Uranium Silicide-derived structured and crystallizes in the tetragonal P4/mmm space group. Ce(1) is bonded to four equivalent Sn(1) and eight equivalent Sn(3) atoms to form CeSn12 cuboctahedra that share corners with four equivalent Ce(1)Sn12 cuboctahedra, corners with eight equivalent La(1)Sn12 cuboctahedra, faces with two equivalent La(1)Sn12 cuboctahedra, and faces with four equivalent Ce(1)Sn12 cuboctahedra. La(1) is bonded to four equivalent Sn(2) and eight equivalent Sn(3) atoms to form LaSn12 cuboctahedra that share corners with four equivalent La(1)Sn12 cuboctahedra, corners with eight equivalent Ce(1)Sn12 cuboctahedra, faces with two equivalent Ce(1)Sn12 cuboctahedra, and faces with four equivalent La(1)Sn12 cuboctahedra. There are three inequivalent Sn sites. In the first Sn site, Sn(1) is bonded in a distorted square co-planar geometry to four equivalent Ce(1) atoms. In the second Sn site, Sn(2) is bonded in a distorted square co-planar geometry to four equivalent La(1) atoms. In the third Sn site, Sn(3) is bonded in a distorted rectangular see-saw-like geometry to two equivalent Ce(1) and two equivalent La(1) atoms. is represented by the CIF file [CIF]
