The structure described by ErPrTl2 is Heusler structured and crystallizes in the tetragonal I4/mmm space group. Er(1) is bonded in a body-centered cubic geometry to eight equivalent Tl(1) atoms. Pr(1) is bonded in a body-centered cubic geometry to eight equivalent Tl(1) atoms. Tl(1) is bonded in a body-centered cubic geometry to four equivalent Er(1) and four equivalent Pr(1) atoms. is represented by the CIF file [CIF]
