Mo4Ru is Tungsten-derived structured and crystallizes in the orthorhombic Fmmm space group. There are two inequivalent Mo sites. In the first Mo site, Mo(1) is bonded in a 8-coordinate geometry to two equivalent Mo(2), four equivalent Mo(1), and two equivalent Ru(1) atoms. In the second Mo site, Mo(2) is bonded in a distorted body-centered cubic geometry to two equivalent Mo(1) and six equivalent Mo(2) atoms. Ru(1) is bonded in a 8-coordinate geometry to four equivalent Mo(1) and four equivalent Ru(1) atoms.
Mo4Ru is Tungsten-derived structured and crystallizes in the orthorhombic Fmmm space group. There are two inequivalent Mo sites. In the first Mo site, Mo(1) is bonded in a 8-coordinate geometry to two equivalent Mo(2), four equivalent Mo(1), and two equivalent Ru(1) atoms. Both Mo(1)-Mo(2) bond lengths are 2.73 Å. All Mo(1)-Mo(1) bond lengths are 2.74 Å. Both Mo(1)-Ru(1) bond lengths are 2.68 Å. In the second Mo site, Mo(2) is bonded in a distorted body-centered cubic geometry to two equivalent Mo(1) and six equivalent Mo(2) atoms. There are two shorter (2.73 Å) and four longer (2.74 Å) Mo(2)-Mo(2) bond lengths. Ru(1) is bonded in a 8-coordinate geometry to four equivalent Mo(1) and four equivalent Ru(1) atoms. All Ru(1)-Ru(1) bond lengths are 2.74 Å.
