The material structure described by Mg2PtSi crystallizes in the hexagonal P6_3/mmc space group. Mg(1) is bonded in a 11-coordinate geometry to four equivalent Mg(1), four equivalent Pt(1), and three equivalent Si(1) atoms. Pt(1) is bonded in a 11-coordinate geometry to eight equivalent Mg(1) and three equivalent Si(1) atoms. Si(1) is bonded in a 9-coordinate geometry to six equivalent Mg(1) and three equivalent Pt(1) atoms. is represented by the CIF file [CIF]
