Materials Data on SbRh by Materials Project

RhSb is Modderite structured and crystallizes in the orthorhombic Pnma space group. The structure is three-dimensional. Rh3+ is bonded to six equivalent Sb3- atoms to form a mixture of distorted face, edge, and corner-sharing RhSb6 octahedra. The corner-sharing octahedra tilt angles range from 46–61°. There are a spread of Rh–Sb bond distances ranging from 2.63–2.80 Å. Sb3- is bonded in a 6-coordinate geometry to six equivalent Rh3+ atoms.
