The crystal structure described by Ho3Rh3Ga8 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 distorted face-sharing HoGa12 cuboctahedra. In the second Ho site, Ho(2) is bonded in a 12-coordinate geometry to two equivalent Rh(1), two equivalent Rh(2), four equivalent Ga(1), and four equivalent Ga(2) atoms. There are two inequivalent Rh sites. In the first Rh site, Rh(1) is bonded in a 8-coordinate geometry to four equivalent Ho(2) and four equivalent Ga(1) atoms. In the second Rh site, Rh(2) is bonded in a 8-coordinate geometry to two equivalent Ho(2), 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 9-coordinate geometry to one Ho(1), two equivalent Ho(2), one Rh(1), two equivalent Rh(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 Rh(2), one Ga(2), and three equivalent Ga(1) atoms. is represented by the CIF file [CIF]
