The material structure described by CeLa4Pd15 is Uranium Silicide-derived structured and crystallizes in the tetragonal P4/mmm space group. Ce(1) is bonded to four equivalent Pd(1) and eight equivalent Pd(4) atoms to form CePd12 cuboctahedra that share corners with four equivalent Ce(1)Pd12 cuboctahedra, corners with eight equivalent La(1)Pd12 cuboctahedra, faces with two equivalent La(1)Pd12 cuboctahedra, faces with four equivalent Ce(1)Pd12 cuboctahedra, and faces with four equivalent Pd(1)Ce4Pd8 cuboctahedra. There are two inequivalent La sites. In the first La site, La(1) is bonded to four equivalent Pd(2), four equivalent Pd(4), and four equivalent Pd(5) atoms to form LaPd12 cuboctahedra that share corners with four equivalent Ce(1)Pd12 cuboctahedra, corners with four equivalent La(1)Pd12 cuboctahedra, corners with four equivalent La(2)Pd12 cuboctahedra, edges with four equivalent Pd(1)Ce4Pd8 cuboctahedra,  a faceface with one Ce(1)Pd12 cuboctahedra,  a faceface with one La(2)Pd12 cuboctahedra, and faces with four equivalent La(1)Pd12 cuboctahedra. In the second La site, La(2) is bonded to four equivalent Pd(3), four equivalent Pd(5), and four equivalent Pd(6) atoms to form a mixture of face and corner-sharing LaPd12 cuboctahedra. There are six inequivalent Pd sites. In the first Pd site, Pd(1) is bonded to four equivalent Ce(1) and eight equivalent Pd(4) atoms to form distorted PdCe4Pd8 cuboctahedra that share corners with four equivalent Pd(1)Ce4Pd8 cuboctahedra, edges with eight equivalent La(1)Pd12 cuboctahedra, faces with four equivalent Ce(1)Pd12 cuboctahedra, and faces with four equivalent Pd(1)Ce4Pd8 cuboctahedra. In the second Pd site, Pd(2) is bonded in a distorted rectangular see-saw-like geometry to four equivalent La(1) atoms. In the third Pd site, Pd(3) is bonded in a distorted rectangular see-saw-like geometry to four equivalent La(2) atoms. In the fourth Pd site, Pd(4) is bonded in a distorted rectangular see-saw-like geometry to two equivalent Ce(1), two equivalent La(1), and two equivalent Pd(1) atoms. In the fifth Pd site, Pd(5) is bonded in a distorted rectangular see-saw-like geometry to two equivalent La(1) and two equivalent La(2) atoms. In the sixth Pd site, Pd(6) is bonded in a distorted square co-planar geometry to four equivalent La(2) atoms. is represented by the Crystallographic Information File (CIF) [CIF]
