Lu5Ru2 crystallizes in the monoclinic C2/c space group. There are three inequivalent Lu sites. In the first Lu site, Lu(1) is bonded in a 2-coordinate geometry to three equivalent Ru(1) atoms. In the second Lu site, Lu(3) is bonded to four equivalent Ru(1) atoms to form distorted edge-sharing LuRu4 tetrahedra. In the third Lu site, Lu(2) is bonded in a 3-coordinate geometry to three equivalent Ru(1) atoms. Ru(1) is bonded in a 8-coordinate geometry to two equivalent Lu(3), three equivalent Lu(1), and three equivalent Lu(2) atoms.
Lu5Ru2 crystallizes in the monoclinic C2/c space group. There are three inequivalent Lu sites. In the first Lu site, Lu(1) is bonded in a 2-coordinate geometry to three equivalent Ru(1) atoms. There are a spread of Lu(1)-Ru(1) bond distances ranging from 2.68-3.28 Å. In the second Lu site, Lu(3) is bonded to four equivalent Ru(1) atoms to form distorted edge-sharing LuRu4 tetrahedra. There are two shorter (2.82 Å) and two longer (2.87 Å) Lu(3)-Ru(1) bond lengths. In the third Lu site, Lu(2) is bonded in a 3-coordinate geometry to three equivalent Ru(1) atoms. There are a spread of Lu(2)-Ru(1) bond distances ranging from 2.75-2.93 Å. Ru(1) is bonded in a 8-coordinate geometry to two equivalent Lu(3), three equivalent Lu(1), and three equivalent Lu(2) atoms.
