Ho2Pd2Si is delta Molybdenum Boride-derived structured and crystallizes in the orthorhombic Pnnm space group. There are two inequivalent Ho sites. In the first Ho site, Ho(1) is bonded in a 9-coordinate geometry to three equivalent Pd(1), four equivalent Pd(2), and two equivalent Si(1) atoms. In the second Ho site, Ho(2) is bonded in a 9-coordinate geometry to two equivalent Pd(2), three equivalent Pd(1), and four equivalent Si(1) atoms. There are two inequivalent Pd sites. In the first Pd site, Pd(1) is bonded in a 7-coordinate geometry to three equivalent Ho(1), three equivalent Ho(2), and one Si(1) atom. In the second Pd site, Pd(2) is bonded in a 9-coordinate geometry to two equivalent Ho(2), four equivalent Ho(1), one Pd(2), and two equivalent Si(1) atoms. Si(1) is bonded in a 10-coordinate geometry to two equivalent Ho(1), four equivalent Ho(2), one Pd(1), two equivalent Pd(2), and one Si(1) atom.
