MgPt2 crystallizes in the hexagonal P-62m space group. Mg(1) is bonded to three equivalent Pt(1) and six equivalent Pt(2) atoms to form a mixture of distorted corner and face-sharing MgPt9 cuboctahedra. There are two inequivalent Pt sites. In the first Pt site, Pt(1) is bonded in a distorted hexagonal planar geometry to six equivalent Mg(1) atoms. In the second Pt site, Pt(2) is bonded to four equivalent Mg(1) atoms to form a mixture of distorted corner and edge-sharing PtMg4 cuboctahedra.
