The structure described by Tm12Fe3In2 crystallizes in the tetragonal I4/mmm space group. There are two inequivalent Tm sites. In the first Tm site, Tm(1) is bonded in a 3-coordinate geometry to one Fe(1), one Fe(2), and two equivalent In(1) atoms. In the second Tm site, Tm(2) is bonded in a 4-coordinate geometry to two equivalent Fe(1) and two equivalent In(1) atoms. There are two inequivalent Fe sites. In the first Fe site, Fe(1) is bonded in a 9-coordinate geometry to four equivalent Tm(1), four equivalent Tm(2), and one Fe(1) atom. In the second Fe site, Fe(2) is bonded in a body-centered cubic geometry to eight equivalent Tm(1) atoms. In(1) is bonded to four equivalent Tm(2) and eight equivalent Tm(1) atoms to form a mixture of distorted corner and face-sharing InTm12 cuboctahedra. is represented by the CIF file [CIF]
