The material described by Er3Pt2Ga9 crystallizes in the orthorhombic Immm space group. There are two inequivalent Er sites. In the first Er site, Er(1) is bonded to four equivalent Ga(3) and eight equivalent Ga(2) atoms to form ErGa12 cuboctahedra that share edges with two equivalent Ga(1)Er4Ga4Pt4 cuboctahedra and faces with two equivalent Er(1)Ga12 cuboctahedra. In the second Er site, Er(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 Er(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 Er(2), four equivalent Pt(1), and four equivalent Ga(3) atoms to form GaEr4Ga4Pt4 cuboctahedra that share edges with two equivalent Er(1)Ga12 cuboctahedra and faces with two equivalent Ga(1)Er4Ga4Pt4 cuboctahedra. In the second Ga site, Ga(2) is bonded in a 9-coordinate geometry to two equivalent Er(1), two equivalent Er(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 Er(1), three equivalent Er(2), two equivalent Pt(1), one Ga(1), and three equivalent Ga(2) atoms. is represented by the CIF card [CIF]
