Materials Data on MoRh3 by Materials Project
MoRh3 is beta Cu3Ti-like structured and crystallizes in the hexagonal P6_3/mmc space group. The structure is three-dimensional. Mo is bonded to twelve equivalent Rh atoms to form MoRh12 cuboctahedra that share corners with six equivalent MoRh12 cuboctahedra, corners with twelve equivalent RhMo4Rh8 cuboctahedra, edges with eighteen equivalent RhMo4Rh8 cuboctahedra, faces with eight equivalent MoRh12 cuboctahedra, and faces with twelve equivalent RhMo4Rh8 cuboctahedra. There are six shorter (2.71 Å) and six longer (2.76 Å) Mo–Rh bond lengths. Rh is bonded to four equivalent Mo and eight equivalent Rh atoms to form RhMo4Rh8 cuboctahedra that share corners with four equivalent MoRh12 cuboctahedra, corners with fourteen equivalent RhMo4Rh8 cuboctahedra, edges with six equivalent MoRh12 cuboctahedra, edges with twelve equivalent RhMo4Rh8 cuboctahedra, faces with four equivalent MoRh12 cuboctahedra, and faces with sixteen equivalent RhMo4Rh8 cuboctahedra. There are a spread of Rh–Rh bond distances ranging from 2.71–2.77 Å.
