The structure described by Tm2Ni2Pb crystallizes in the orthorhombic Cmmm space group. Tm(1) is bonded in a 10-coordinate geometry to six equivalent Ni(1) and four equivalent Pb(1) atoms. Ni(1) is bonded in a 9-coordinate geometry to six equivalent Tm(1), two equivalent Ni(1), and one Pb(1) atom. Pb(1) is bonded in a 10-coordinate geometry to eight equivalent Tm(1) and two equivalent Ni(1) atoms. is represented by the CIF card [CIF]
