Materials Data on Sb2Rh by Materials Project
RhSb2 is Marcasite-like structured and crystallizes in the monoclinic P2_1/c space group. The structure is three-dimensional. Rh4+ is bonded to six Sb2- atoms to form a mixture of edge and corner-sharing RhSb6 octahedra. The corner-sharing octahedra tilt angles range from 51–57°. There are a spread of Rh–Sb bond distances ranging from 2.62–2.71 Å. There are two inequivalent Sb2- sites. In the first Sb2- site, Sb2- is bonded in a 4-coordinate geometry to three equivalent Rh4+ atoms. In the second Sb2- site, Sb2- is bonded in a 4-coordinate geometry to three equivalent Rh4+ atoms.
