Materials Data on CrB4Mo by Materials Project
MoCrB4 is hexagonal omega structure-derived structured and crystallizes in the hexagonal P6/mmm space group. The structure is three-dimensional. Mo3+ is bonded to twelve equivalent B+1.50- atoms to form MoB12 cuboctahedra that share edges with twelve equivalent CrB12 cuboctahedra, faces with two equivalent CrB12 cuboctahedra, and faces with six equivalent MoB12 cuboctahedra. All Mo–B bond lengths are 2.41 Å. Cr3+ is bonded to twelve equivalent B+1.50- atoms to form CrB12 cuboctahedra that share edges with twelve equivalent MoB12 cuboctahedra, faces with two equivalent MoB12 cuboctahedra, and faces with six equivalent CrB12 cuboctahedra. All Cr–B bond lengths are 2.28 Å. B+1.50- is bonded in a 9-coordinate geometry to three equivalent Mo3+, three equivalent Cr3+, and three equivalent B+1.50- atoms. All B–B bond lengths are 1.74 Å.
