The crystal structure described by MgGd2Tl is Heusler structured and crystallizes in the tetragonal I4/mmm space group. Mg(1) is bonded in a body-centered cubic geometry to eight equivalent Gd(1) atoms. Gd(1) is bonded in a body-centered cubic geometry to four equivalent Mg(1) and four equivalent Tl(1) atoms. Tl(1) is bonded in a body-centered cubic geometry to eight equivalent Gd(1) atoms. is represented by the Crystallographic Information File (CIF) [CIF]
