The material structure described by MgSmPt crystallizes in the hexagonal P-62m space group. Mg(1) is bonded in a 4-coordinate geometry to two equivalent Pt(1) and two equivalent Pt(2) atoms. Sm(1) is bonded in a 5-coordinate geometry to one Pt(1) and four equivalent Pt(2) atoms. There are two inequivalent Pt sites. In the first Pt site, Pt(1) is bonded in a 9-coordinate geometry to six equivalent Mg(1) and three equivalent Sm(1) atoms. In the second Pt site, Pt(2) is bonded in a 9-coordinate geometry to three equivalent Mg(1) and six equivalent Sm(1) atoms. is represented by the CIF card [CIF]
