Materials Data on SbRh2 by Materials Project
Rh2Sb is Cotunnite structured and crystallizes in the orthorhombic Pnma space group. The structure is three-dimensional. there are two inequivalent Rh sites. In the first Rh site, Rh is bonded in a 3-coordinate geometry to five equivalent Sb atoms. There are a spread of Rh–Sb bond distances ranging from 2.68–2.99 Å. In the second Rh site, Rh is bonded to five equivalent Sb atoms to form a mixture of distorted edge and corner-sharing RhSb5 tetrahedra. There are a spread of Rh–Sb bond distances ranging from 2.61–3.27 Å. Sb is bonded in a 10-coordinate geometry to ten Rh atoms.
