FePtSb is half-Heusler structured and crystallizes in the cubic F-43m space group. Fe(1) is bonded in a body-centered cubic geometry to four equivalent Pt(1) and four equivalent Sb(1) atoms. Pt(1) is bonded to four equivalent Fe(1) and six equivalent Sb(1) atoms to form a mixture of distorted corner and face-sharing PtFe4Sb6 tetrahedra. Sb(1) is bonded in a 10-coordinate geometry to four equivalent Fe(1) and six equivalent Pt(1) atoms.
