Materials Data on MoRu by Materials Project

RuMo is Magnesium-derived structured and crystallizes in the hexagonal P-6m2 space group. The structure is three-dimensional. Mo is bonded to six equivalent Mo and six equivalent Ru atoms to form MoMo6Ru6 cuboctahedra that share corners with eighteen equivalent MoMo6Ru6 cuboctahedra, edges with six equivalent MoMo6Ru6 cuboctahedra, edges with twelve equivalent RuMo6Ru6 cuboctahedra, faces with eight equivalent MoMo6Ru6 cuboctahedra, and faces with twelve equivalent RuMo6Ru6 cuboctahedra. All Mo–Mo bond lengths are 2.78 Å. All Mo–Ru bond lengths are 2.75 Å. Ru is bonded to six equivalent Mo and six equivalent Ru atoms to form RuMo6Ru6 cuboctahedra that share corners with eighteen equivalent RuMo6Ru6 cuboctahedra, edges with six equivalent RuMo6Ru6 cuboctahedra, edges with twelve equivalent MoMo6Ru6 cuboctahedra, faces with eight equivalent RuMo6Ru6 cuboctahedra, and faces with twelve equivalent MoMo6Ru6 cuboctahedra. All Ru–Ru bond lengths are 2.78 Å.

Materials Data on Mo4Ru by Materials Project

Mo4Ru is Tungsten-derived structured and crystallizes in the orthorhombic Fmmm space group. The structure is three-dimensional. there are two inequivalent Mo sites. In the first Mo site, Mo is bonded in a 8-coordinate geometry to six Mo and two equivalent Ru atoms. There are two shorter (2.73 Å) and four longer (2.74 Å) Mo–Mo bond lengths. Both Mo–Ru bond lengths are 2.68 Å. In the second Mo site, Mo is bonded in a distorted body-centered cubic geometry to eight Mo atoms. There are two shorter (2.73 Å) and four longer (2.74 Å) Mo–Mo bond lengths. Ru is bonded in a 8-coordinate geometry to four equivalent Mo and four equivalent Ru atoms. All Ru–Ru bond lengths are 2.74 Å.
