The material structure described by Tm5(Ir2Ge5)2 crystallizes in the tetragonal P4/mbm space group. There are three inequivalent Tm sites. In the first Tm site, Tm(1) is bonded in a 16-coordinate geometry to four equivalent Ir(1), four equivalent Ge(2), and eight equivalent Ge(3) atoms. In the second Tm site, Tm(2) is bonded to four equivalent Ir(1), two equivalent Ge(1), two equivalent Ge(3), and four equivalent Ge(2) atoms to form distorted face-sharing TmGe8Ir4 cuboctahedra. In the third Tm site, Tm(3) is bonded in a 14-coordinate geometry to four equivalent Ir(1), two equivalent Ge(3), four equivalent Ge(1), and four equivalent Ge(2) atoms. Ir(1) is bonded in a 10-coordinate geometry to one Tm(1), two equivalent Tm(2), two equivalent Tm(3), one Ge(1), two equivalent Ge(2), and two equivalent Ge(3) atoms. There are three inequivalent Ge sites. In the first Ge site, Ge(1) is bonded in a 9-coordinate geometry to two equivalent Tm(2), four equivalent Tm(3), two equivalent Ir(1), and one Ge(1) atom. In the second Ge site, Ge(2) is bonded in a 8-coordinate geometry to one Tm(1), two equivalent Tm(2), two equivalent Tm(3), two equivalent Ir(1), and one Ge(2) atom. In the third Ge site, Ge(3) is bonded in a 8-coordinate geometry to one Tm(2), one Tm(3), two equivalent Tm(1), two equivalent Ir(1), and two equivalent Ge(3) atoms. is represented by the Crystallographic Information File (CIF) [CIF]
