The crystal structure described by TmNiGe2 crystallizes in the orthorhombic Immm space group. There are two inequivalent Tm sites. In the first Tm site, Tm(1) is bonded in a 8-coordinate geometry to six equivalent Ni(1), two equivalent Ge(1), and six equivalent Ge(2) atoms. In the second Tm site, Tm(2) is bonded in a 14-coordinate geometry to four equivalent Ni(1), two equivalent Ge(2), four equivalent Ge(1), and four equivalent Ge(3) atoms. Ni(1) is bonded in a 10-coordinate geometry to two equivalent Tm(2), three equivalent Tm(1), one Ge(1), one Ge(3), and three equivalent Ge(2) 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(1), four equivalent Tm(2), two equivalent Ni(1), and one Ge(1) atom. In the second Ge site, Ge(2) is bonded in a 8-coordinate geometry to one Tm(2), three equivalent Tm(1), three equivalent Ni(1), and one Ge(2) atom. In the third Ge site, Ge(3) is bonded in a 7-coordinate geometry to four equivalent Tm(2), two equivalent Ni(1), and one Ge(3) atom. is represented by the CIF file [CIF]
