Materials Data on Sb3Rh by Materials Project
RhSb3 is Skutterudite structured and crystallizes in the cubic Im-3 space group. The structure is three-dimensional. Rh3+ is bonded to six equivalent Sb1- atoms to form corner-sharing RhSb6 octahedra. The corner-sharing octahedral tilt angles are 55°. All Rh–Sb bond lengths are 2.65 Å. Sb1- is bonded in a distorted bent 120 degrees geometry to two equivalent Rh3+ and two equivalent Sb1- atoms. There are one shorter (2.91 Å) and one longer (3.00 Å) Sb–Sb bond lengths.
