The compound described by CeLa(CuSi)4 crystallizes in the tetragonal P4/mmm space group. Ce(1) is bonded in a 16-coordinate geometry to eight equivalent Cu(1) and eight equivalent Si(1) atoms. La(1) is bonded in a 16-coordinate geometry to eight equivalent Cu(1) and eight equivalent Si(2) atoms. Cu(1) is bonded to two equivalent Ce(1), two equivalent La(1), two equivalent Si(1), and two equivalent Si(2) atoms to form a mixture of distorted edge, face, and corner-sharing CuLa2Ce2Si4 cuboctahedra. There are two inequivalent Si sites. In the first Si site, Si(1) is bonded in a 9-coordinate geometry to four equivalent Ce(1), four equivalent Cu(1), and one Si(1) atom. In the second Si site, Si(2) is bonded in a 9-coordinate geometry to four equivalent La(1), four equivalent Cu(1), and one Si(2) atom. is represented by the CIF card [CIF]
