The structure described by FePt is Tetraauricupride structured and crystallizes in the tetragonal P4/mmm space group. Fe(1) is bonded to four equivalent Fe(1) and eight equivalent Pt(1) atoms to form distorted FeFe4Pt8 cuboctahedra that share corners with twelve equivalent Fe(1)Fe4Pt8 cuboctahedra, edges with eight equivalent Fe(1)Fe4Pt8 cuboctahedra, edges with sixteen equivalent Pt(1)Fe8Pt4 cuboctahedra, faces with eight equivalent Pt(1)Fe8Pt4 cuboctahedra, and faces with ten equivalent Fe(1)Fe4Pt8 cuboctahedra.
