The crystal structure described by Tb3Pt2Ga9 crystallizes in the orthorhombic Immm space group. There are two inequivalent Tb sites. In the first Tb site, Tb(1) is bonded to four equivalent Ga(3) and eight equivalent Ga(2) atoms to form TbGa12 cuboctahedra that share edges with two equivalent Ga(1)Tb4Ga4Pt4 cuboctahedra and faces with two equivalent Tb(1)Ga12 cuboctahedra. In the second Tb site, Tb(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 Tb(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 Tb(2), four equivalent Pt(1), and four equivalent Ga(3) atoms to form GaTb4Ga4Pt4 cuboctahedra that share edges with two equivalent Tb(1)Ga12 cuboctahedra and faces with two equivalent Ga(1)Tb4Ga4Pt4 cuboctahedra. In the second Ga site, Ga(2) is bonded in a 9-coordinate geometry to two equivalent Tb(1), two equivalent Tb(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 Tb(1), three equivalent Tb(2), two equivalent Pt(1), one Ga(1), and three equivalent Ga(2) atoms. is represented by the CIF card [CIF]
