The material structure described by MgTm2Cu2 crystallizes in the tetragonal P4/mbm space group. Mg(1) is bonded in a distorted square co-planar geometry to four equivalent Cu(1) atoms. Tm(1) is bonded in a 6-coordinate geometry to six equivalent Cu(1) atoms. Cu(1) is bonded in a 9-coordinate geometry to two equivalent Mg(1), six equivalent Tm(1), and one Cu(1) atom. is represented by the Crystallographic Information File (CIF) [CIF]
