Materials Data on Rh2S3 by Materials Project

Rh2S3 is Corundum-like structured and crystallizes in the orthorhombic Pbcn space group. The structure is three-dimensional. Rh3+ is bonded to six S2- atoms to form a mixture of face, edge, and corner-sharing RhS6 octahedra. The corner-sharing octahedra tilt angles range from 49–70°. There are a spread of Rh–S bond distances ranging from 2.33–2.43 Å. There are two inequivalent S2- sites. In the first S2- site, S2- is bonded to four equivalent Rh3+ atoms to form a mixture of distorted edge and corner-sharing SRh4 trigonal pyramids. In the second S2- site, S2- is bonded to four equivalent Rh3+ atoms to form a mixture of distorted edge and corner-sharing SRh4 tetrahedra.
