The structure described by Ho3Pt2Ga9 crystallizes in the orthorhombic Immm space group. There are two inequivalent Ho sites. In the first Ho site, Ho(1) is bonded to four equivalent Ga(3) and eight equivalent Ga(2) atoms to form HoGa12 cuboctahedra that share edges with two equivalent Ga(1)Ho4Ga4Pt4 cuboctahedra and faces with two equivalent Ho(1)Ga12 cuboctahedra. In the second Ho site, Ho(2) is bonded in a 14-coordinate geometry to two equivalent Pt(1), two equivalent Ga(1), four equivalent Ga(2), and six equivalent Ga(3) atoms. Pt(1) is bonded in a 10-coordinate geometry to two equivalent Ho(2), two equivalent Ga(1), two equivalent Ga(2), and four equivalent Ga(3) atoms. There are three inequivalent Ga sites. In the first Ga site, Ga(1) is bonded to four equivalent Ho(2), four equivalent Pt(1), and four equivalent Ga(3) atoms to form GaHo4Ga4Pt4 cuboctahedra that share edges with two equivalent Ho(1)Ga12 cuboctahedra and faces with two equivalent Ga(1)Ho4Ga4Pt4 cuboctahedra. In the second Ga site, Ga(2) is bonded in a 9-coordinate geometry to two equivalent Ho(1), two equivalent Ho(2), one Pt(1), one Ga(2), and three equivalent Ga(3) atoms. In the third Ga site, Ga(3) is bonded in a 10-coordinate geometry to one Ho(1), three equivalent Ho(2), two equivalent Pt(1), one Ga(1), and three equivalent Ga(2) atoms. is represented by the Crystallographic Information File (CIF) [CIF]
