LaPd5 crystallizes in the hexagonal P6/mmm space group. La(1) is bonded in a distorted hexagonal planar geometry to six equivalent Pd(2) and twelve equivalent Pd(1) atoms. There are two inequivalent Pd sites. In the first Pd site, Pd(1) is bonded to four equivalent La(1), four equivalent Pd(1), and four equivalent Pd(2) atoms to form a mixture of face, corner, and edge-sharing PdLa4Pd8 cuboctahedra. In the second Pd site, Pd(2) is bonded in a 3-coordinate geometry to three equivalent La(1) and six equivalent Pd(1) atoms.
