The material described by MgPt2 crystallizes in the monoclinic C2/m space group. Mg(1) is bonded in a 9-coordinate geometry to four equivalent Pt(1) and five equivalent Pt(2) atoms. There are two inequivalent Pt sites. In the first Pt site, Pt(1) is bonded in a 4-coordinate geometry to four equivalent Mg(1) atoms. In the second Pt site, Pt(2) is bonded in a 5-coordinate geometry to five equivalent Mg(1) atoms. is represented by the CIF card [CIF]
