The structure described by Tm5Ge4 crystallizes in the orthorhombic Pnma space group. There are three inequivalent Tm sites. In the first Tm site, Tm(1) is bonded in a 6-coordinate geometry to one Ge(3), two equivalent Ge(2), and three equivalent Ge(1) atoms. In the second Tm site, Tm(2) is bonded in a 7-coordinate geometry to one Ge(2), two equivalent Ge(3), and four equivalent Ge(1) atoms. In the third Tm site, Tm(3) is bonded to two equivalent Ge(1), two equivalent Ge(2), and two equivalent Ge(3) atoms to form corner-sharing TmGe6 octahedra. The corner-sharing octahedral tilt angles range from 51-53°. There are three inequivalent Ge sites. In the first Ge site, Ge(3) is bonded in a 9-coordinate geometry to two equivalent Tm(1), two equivalent Tm(3), four equivalent Tm(2), and one Ge(2) atom. In the second Ge site, Ge(1) is bonded in a 8-coordinate geometry to one Tm(3), three equivalent Tm(1), and four equivalent Tm(2) atoms. In the third Ge site, Ge(2) is bonded in a 9-coordinate geometry to two equivalent Tm(2), two equivalent Tm(3), four equivalent Tm(1), and one Ge(3) atom. is represented by the CIF file [CIF]
