Materials Data on Mo2Rh by Materials Project
Mo2Rh is beta-derived structured and crystallizes in the orthorhombic Fmmm space group. The structure is three-dimensional. Mo is bonded to eight equivalent Mo and four equivalent Rh atoms to form distorted MoMo8Rh4 cuboctahedra that share corners with four equivalent RhMo8Rh4 cuboctahedra, corners with eight equivalent MoMo8Rh4 cuboctahedra, edges with twelve equivalent MoMo8Rh4 cuboctahedra, edges with twelve equivalent RhMo8Rh4 cuboctahedra, faces with five equivalent RhMo8Rh4 cuboctahedra, and faces with thirteen equivalent MoMo8Rh4 cuboctahedra. There are a spread of Mo–Mo bond distances ranging from 2.72–2.99 Å. There are two shorter (2.73 Å) and two longer (2.80 Å) Mo–Rh bond lengths. Rh is bonded to eight equivalent Mo and four equivalent Rh atoms to form RhMo8Rh4 cuboctahedra that share corners with four equivalent RhMo8Rh4 cuboctahedra, corners with eight equivalent MoMo8Rh4 cuboctahedra, edges with twenty-four equivalent MoMo8Rh4 cuboctahedra, faces with eight equivalent RhMo8Rh4 cuboctahedra, and faces with ten equivalent MoMo8Rh4 cuboctahedra. All Rh–Rh bond lengths are 2.72 Å.
