The material structure described by TmMg2 crystallizes in the trigonal P-3m1 space group. Mg(1) is bonded in a 11-coordinate geometry to five equivalent Mg(1) and six equivalent Tm(1) atoms. Tm(1) is bonded in a 14-coordinate geometry to twelve equivalent Mg(1) and two equivalent Tm(1) atoms. is represented by the CIF file [CIF]
