The structure described by Ho2PdSi3 is hexagonal omega structure-derived structured and crystallizes in the orthorhombic Pmm2 space group. There are two inequivalent Ho sites. In the first Ho site, Ho(1) is bonded to two equivalent Pd(1), two equivalent Si(3), four equivalent Si(1), and four equivalent Si(2) atoms to form HoSi10Pd2 cuboctahedra that share edges with four equivalent Ho(1)Si10Pd2 cuboctahedra, edges with eight equivalent Ho(2)Si8Pd4 cuboctahedra, faces with four equivalent Ho(1)Si10Pd2 cuboctahedra, and faces with four equivalent Ho(2)Si8Pd4 cuboctahedra. In the second Ho site, Ho(2) is bonded to four equivalent Pd(1), two equivalent Si(1), two equivalent Si(2), and four equivalent Si(3) atoms to form HoSi8Pd4 cuboctahedra that share edges with four equivalent Ho(2)Si8Pd4 cuboctahedra, edges with eight equivalent Ho(1)Si10Pd2 cuboctahedra, faces with four equivalent Ho(1)Si10Pd2 cuboctahedra, and faces with four equivalent Ho(2)Si8Pd4 cuboctahedra. Pd(1) is bonded in a 9-coordinate geometry to two equivalent Ho(1), four equivalent Ho(2), one Si(3), and two equivalent Si(2) atoms. There are three inequivalent Si sites. In the first Si site, Si(1) is bonded in a 9-coordinate geometry to two equivalent Ho(2), four equivalent Ho(1), one Si(2), and two equivalent Si(3) atoms. In the second Si site, Si(2) is bonded in a 9-coordinate geometry to two equivalent Ho(2), four equivalent Ho(1), two equivalent Pd(1), and one Si(1) atom. In the third Si site, Si(3) is bonded in a 9-coordinate geometry to two equivalent Ho(1), four equivalent Ho(2), one Pd(1), and two equivalent Si(1) atoms. is represented by the CIF file [CIF]
