The structure described by Ho2(PdAl3)3 crystallizes in the orthorhombic Cmcm space group. Ho(1) is bonded in a 17-coordinate geometry to two equivalent Pd(2), four equivalent Pd(1), one Al(1), two equivalent Al(3), two equivalent Al(4), and six equivalent Al(2) atoms. There are two inequivalent Pd sites. In the first Pd site, Pd(1) is bonded in a 8-coordinate geometry to four equivalent Ho(1), two equivalent Al(3), two equivalent Al(4), and four equivalent Al(2) atoms. In the second Pd site, Pd(2) is bonded in a 8-coordinate geometry to four equivalent Ho(1), two equivalent Al(1), two equivalent Al(3), and four equivalent Al(2) atoms. There are four inequivalent Al sites. In the first Al site, Al(1) is bonded in a 2-coordinate geometry to two equivalent Ho(1) and two equivalent Pd(2) atoms. In the second Al site, Al(2) is bonded in a 3-coordinate geometry to three equivalent Ho(1), one Pd(2), two equivalent Pd(1), and one Al(3) atom. In the third Al site, Al(3) is bonded in a 10-coordinate geometry to two equivalent Ho(1), one Pd(2), two equivalent Pd(1), one Al(3), two equivalent Al(2), and two equivalent Al(4) atoms. In the fourth Al site, Al(4) is bonded in a 2-coordinate geometry to two equivalent Ho(1), two equivalent Pd(1), and two equivalent Al(3) atoms. is represented by the Crystallographic Information File (CIF) [CIF]
