FeZnSb is half-Heusler structured and crystallizes in the cubic F-43m space group. Fe(1) is bonded to six equivalent Zn(1) and four equivalent Sb(1) atoms to form distorted FeZn6Sb4 tetrahedra that share corners with four equivalent Zn(1)Fe6Sb4 tetrahedra, corners with six equivalent Fe(1)Zn6Sb4 tetrahedra, edges with six equivalent Zn(1)Fe6Sb4 tetrahedra, and faces with twelve equivalent Fe(1)Zn6Sb4 tetrahedra. Zn(1) is bonded to six equivalent Fe(1) and four equivalent Sb(1) atoms to form distorted ZnFe6Sb4 tetrahedra that share corners with four equivalent Fe(1)Zn6Sb4 tetrahedra, corners with six equivalent Zn(1)Fe6Sb4 tetrahedra, edges with six equivalent Fe(1)Zn6Sb4 tetrahedra, and faces with twelve equivalent Zn(1)Fe6Sb4 tetrahedra. Sb(1) is bonded in a body-centered cubic geometry to four equivalent Fe(1) and four equivalent Zn(1) atoms.
