The material described by TmNiGe3 crystallizes in the orthorhombic Cmmm space group. Tm(1) is bonded in a 14-coordinate geometry to four equivalent Ni(1), two equivalent Ge(2), two equivalent Ge(3), and six equivalent Ge(1) atoms. Ni(1) is bonded in a 9-coordinate geometry to four equivalent Tm(1), 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 six equivalent Tm(1), one Ni(1), and two equivalent Ge(1) atoms. In the second Ge site, Ge(2) is bonded in a 9-coordinate geometry to two equivalent Tm(1), two equivalent Ni(1), one Ge(2), and four equivalent Ge(3) atoms. In the third Ge site, Ge(3) is bonded in a 9-coordinate geometry to two equivalent Tm(1), two equivalent Ni(1), one Ge(3), and four equivalent Ge(2) atoms. is represented by the CIF file [CIF]
