The crystal structure described by AlPd5 crystallizes in the orthorhombic Pnma space group. There are five inequivalent Pd sites. In the first Pd site, Pd(1) is bonded in a 3-coordinate geometry to two equivalent Pd(2) and three equivalent Al(1) atoms. In the second Pd site, Pd(2) is bonded to two equivalent Pd(1), two equivalent Pd(4), three equivalent Pd(3), three equivalent Pd(5), and two equivalent Al(1) atoms to form a mixture of distorted corner, edge, and face-sharing PdAl2Pd10 cuboctahedra. In the third Pd site, Pd(3) is bonded in a 3-coordinate geometry to three equivalent Pd(2) and three equivalent Al(1) atoms. In the fourth Pd site, Pd(4) is bonded in a distorted single-bond geometry to two equivalent Pd(2) and one Al(1) atom. In the fifth Pd site, Pd(5) is bonded in a distorted single-bond geometry to three equivalent Pd(2) and one Al(1) atom. Al(1) is bonded in a 10-coordinate geometry to one Pd(4), one Pd(5), two equivalent Pd(2), three equivalent Pd(1), and three equivalent Pd(3) atoms. is represented by the CIF file [CIF]
