The material structure described by Tm2Fe17 crystallizes in the hexagonal P6_3/mmc space group. There are two inequivalent Tm sites. In the first Tm site, Tm(1) is bonded in a 18-coordinate geometry to six equivalent Fe(3) and twelve equivalent Fe(4) atoms. In the second Tm site, Tm(2) is bonded in a 20-coordinate geometry to two equivalent Fe(1), six equivalent Fe(2), six equivalent Fe(3), and six equivalent Fe(4) atoms. There are four inequivalent Fe sites. In the first Fe site, Fe(1) is bonded in a 14-coordinate geometry to one Tm(2), one Fe(1), three equivalent Fe(2), three equivalent Fe(4), and six equivalent Fe(3) atoms. In the second Fe site, Fe(2) is bonded to two equivalent Tm(2), two equivalent Fe(1), four equivalent Fe(3), and four equivalent Fe(4) atoms to form FeTm2Fe10 cuboctahedra that share corners with four equivalent Fe(2)Tm2Fe10 cuboctahedra, corners with ten equivalent Fe(4)Tm3Fe9 cuboctahedra, edges with six equivalent Fe(4)Tm3Fe9 cuboctahedra, faces with four equivalent Fe(4)Tm3Fe9 cuboctahedra, and faces with six equivalent Fe(2)Tm2Fe10 cuboctahedra. In the third Fe site, Fe(3) is bonded in a 12-coordinate geometry to one Tm(1), one Tm(2), two equivalent Fe(1), two equivalent Fe(2), two equivalent Fe(3), and four equivalent Fe(4) atoms. In the fourth Fe site, Fe(4) is bonded to one Tm(2), two equivalent Tm(1), one Fe(1), two equivalent Fe(2), two equivalent Fe(4), and four equivalent Fe(3) atoms to form distorted FeTm3Fe9 cuboctahedra that share corners with five equivalent Fe(2)Tm2Fe10 cuboctahedra, corners with ten equivalent Fe(4)Tm3Fe9 cuboctahedra, edges with three equivalent Fe(2)Tm2Fe10 cuboctahedra, edges with five equivalent Fe(4)Tm3Fe9 cuboctahedra, faces with two equivalent Fe(2)Tm2Fe10 cuboctahedra, and faces with eight equivalent Fe(4)Tm3Fe9 cuboctahedra. is represented by the CIF file [CIF]
