Sb Mo Rh Rh
MoRh2Sb crystallizes in the monoclinic Cm space group. Mo(1) is bonded in a distorted square co-planar geometry to one Rh(2) and four equivalent Sb(1) atoms. The Mo(1)-Rh(2) bond length is 3.15 Å. There are a spread of Mo(1)-Sb(1) bond distances ranging from 2.06-2.24 Å. There are two inequivalent Rh sites. In the first Rh site, Rh(1) is bonded in a 5-coordinate geometry to four equivalent Rh(2) and one Sb(1) atom. There are a spread of Rh(1)-Rh(2) bond distances ranging from 2.20-2.37 Å. The Rh(1)-Sb(1) bond length is 3.26 Å. In the second Rh site, Rh(2) is bonded in a 5-coordinate geometry to one Mo(1) and four equivalent Rh(1) atoms. Sb(1) is bonded in a distorted square co-planar geometry to four equivalent Mo(1) and one Rh(1) atom.
