The structure described by Tm6CoBi2 crystallizes in the hexagonal P-62m space group. There are two inequivalent Tm sites. In the first Tm site, Tm(1) is bonded in a 5-coordinate geometry to one Co(1) and four equivalent Bi(1) atoms. In the second Tm site, Tm(2) is bonded in a 4-coordinate geometry to two equivalent Co(1) and two equivalent Bi(1) atoms. Co(1) is bonded in a 9-coordinate geometry to three equivalent Tm(1) and six equivalent Tm(2) atoms. Bi(1) is bonded in a 9-coordinate geometry to three equivalent Tm(2) and six equivalent Tm(1) atoms. is represented by the CIF file [CIF]
