CaPd5 crystallizes in the hexagonal P6/mmm space group. Ca(1) is bonded in a distorted hexagonal planar geometry to six equivalent Pd(1) and twelve equivalent Pd(2) atoms. There are two inequivalent Pd sites. In the first Pd site, Pd(1) is bonded in a 3-coordinate geometry to three equivalent Ca(1) and six equivalent Pd(2) atoms. In the second Pd site, Pd(2) is bonded to four equivalent Ca(1), four equivalent Pd(1), and four equivalent Pd(2) atoms to form a mixture of face, corner, and edge-sharing PdCa4Pd8 cuboctahedra.
