The material structure described by FeSb3 is Skutterudite structured and crystallizes in the cubic Im-3 space group. Fe(1) is bonded to six equivalent Sb(1) atoms to form corner-sharing FeSb6 octahedra. The corner-sharing octahedral tilt angles are 54°. Sb(1) is bonded in a distorted bent 120 degrees geometry to two equivalent Fe(1) atoms. is represented by the Crystallographic Information File (CIF) [CIF]
