The crystal structure described by Ho3Ag3Ga8 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(1) and eight equivalent Ga(2) atoms to form HoGa12 cuboctahedra that share edges with two equivalent Ag(1)Ho4Ga4Ag4 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 Ag(1), two equivalent Ag(2), four equivalent Ga(2), and six equivalent Ga(1) atoms. There are two inequivalent Ag sites. In the first Ag site, Ag(1) is bonded to four equivalent Ho(2), four equivalent Ag(2), and four equivalent Ga(1) atoms to form distorted AgHo4Ga4Ag4 cuboctahedra that share edges with two equivalent Ho(1)Ga12 cuboctahedra and faces with two equivalent Ag(1)Ho4Ga4Ag4 cuboctahedra. In the second Ag site, Ag(2) is bonded in a 10-coordinate geometry to two equivalent Ho(2), two equivalent Ag(1), two equivalent Ga(2), and four equivalent Ga(1) atoms. There are two inequivalent Ga sites. In the first Ga site, Ga(1) is bonded in a 10-coordinate geometry to one Ho(1), three equivalent Ho(2), one Ag(1), two equivalent Ag(2), and three equivalent Ga(2) atoms. In the second Ga site, Ga(2) is bonded in a 9-coordinate geometry to two equivalent Ho(1), two equivalent Ho(2), one Ag(2), one Ga(2), and three equivalent Ga(1) atoms. is represented by the CIF file [CIF]
