The material structure described by Fe2Pt is beta-derived structured and crystallizes in the trigonal P-3m1 space group. Fe(1) is bonded to nine equivalent Fe(1) and three equivalent Pt(1) atoms to form distorted FeFe9Pt3 cuboctahedra that share corners with three equivalent Pt(1)Fe6Pt6 cuboctahedra, corners with nine equivalent Fe(1)Fe9Pt3 cuboctahedra, edges with nine equivalent Pt(1)Fe6Pt6 cuboctahedra, edges with fifteen equivalent Fe(1)Fe9Pt3 cuboctahedra, faces with six equivalent Pt(1)Fe6Pt6 cuboctahedra, and faces with twelve equivalent Fe(1)Fe9Pt3 cuboctahedra. Pt(1) is bonded to six equivalent Fe(1) and six equivalent Pt(1) atoms to form PtFe6Pt6 cuboctahedra that share corners with six equivalent Fe(1)Fe9Pt3 cuboctahedra, corners with six equivalent Pt(1)Fe6Pt6 cuboctahedra, edges with six equivalent Pt(1)Fe6Pt6 cuboctahedra, edges with eighteen equivalent Fe(1)Fe9Pt3 cuboctahedra, faces with six equivalent Pt(1)Fe6Pt6 cuboctahedra, and faces with twelve equivalent Fe(1)Fe9Pt3 cuboctahedra. is represented by the CIF file [CIF]
