FePt3 is Uranium Silicide structured and crystallizes in the cubic Pm-3m space group. Fe(1) is bonded to twelve equivalent Pt(1) atoms to form FePt12 cuboctahedra that share corners with twelve equivalent Fe(1)Pt12 cuboctahedra, edges with twenty-four equivalent Pt(1)Fe4Pt8 cuboctahedra, faces with six equivalent Fe(1)Pt12 cuboctahedra, and faces with twelve equivalent Pt(1)Fe4Pt8 cuboctahedra. Pt(1) is bonded to four equivalent Fe(1) and eight equivalent Pt(1) atoms to form distorted PtFe4Pt8 cuboctahedra that share corners with twelve equivalent Pt(1)Fe4Pt8 cuboctahedra, edges with eight equivalent Fe(1)Pt12 cuboctahedra, edges with sixteen equivalent Pt(1)Fe4Pt8 cuboctahedra, faces with four equivalent Fe(1)Pt12 cuboctahedra, and faces with fourteen equivalent Pt(1)Fe4Pt8 cuboctahedra.
