Fe3Pt is Uranium Silicide structured and crystallizes in the cubic Pm-3m space group. Fe(1) is bonded to eight equivalent Fe(1) and four equivalent Pt(1) atoms to form distorted FeFe8Pt4 cuboctahedra that share corners with twelve equivalent Fe(1)Fe8Pt4 cuboctahedra, edges with eight equivalent Pt(1)Fe12 cuboctahedra, edges with sixteen equivalent Fe(1)Fe8Pt4 cuboctahedra, faces with four equivalent Pt(1)Fe12 cuboctahedra, and faces with fourteen equivalent Fe(1)Fe8Pt4 cuboctahedra. Pt(1) is bonded to twelve equivalent Fe(1) atoms to form PtFe12 cuboctahedra that share corners with twelve equivalent Pt(1)Fe12 cuboctahedra, edges with twenty-four equivalent Fe(1)Fe8Pt4 cuboctahedra, faces with six equivalent Pt(1)Fe12 cuboctahedra, and faces with twelve equivalent Fe(1)Fe8Pt4 cuboctahedra.
