The material structure described by TmGe3 crystallizes in the orthorhombic Cmcm space group. Tm(1) is bonded in a 10-coordinate geometry to two equivalent Ge(2), two equivalent Ge(3), and six equivalent Ge(1) atoms. There are three inequivalent Ge sites. In the first Ge site, Ge(3) is bonded in a 7-coordinate geometry to two equivalent Tm(1) and five equivalent Ge(2) atoms. In the second Ge site, Ge(1) is bonded in a 8-coordinate geometry to six equivalent Tm(1) and two equivalent Ge(1) atoms. In the third Ge site, Ge(2) is bonded in a 7-coordinate geometry to two equivalent Tm(1) and five equivalent Ge(3) atoms. is represented by the CIF file [CIF]
