The structure described by CeLa(PdSi)4 crystallizes in the tetragonal P4/mmm space group. Ce(1) is bonded in a 16-coordinate geometry to eight equivalent Pd(1) and eight equivalent Si(1) atoms. La(1) is bonded in a 16-coordinate geometry to eight equivalent Pd(1) and eight equivalent Si(2) atoms. Pd(1) is bonded in a 4-coordinate geometry to two equivalent Ce(1), two equivalent La(1), two equivalent Si(1), and two equivalent Si(2) atoms. 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 Pd(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 Pd(1), and one Si(2) atom. is represented by the Crystallographic Information File (CIF) [CIF]
