Y5Ru2 crystallizes in the monoclinic C2/c space group. There are three inequivalent Y sites. In the first Y site, Y(1) is bonded in a 2-coordinate geometry to three equivalent Ru(1) atoms. In the second Y site, Y(3) is bonded to four equivalent Ru(1) atoms to form distorted edge-sharing YRu4 tetrahedra. In the third Y site, Y(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 Y(3), three equivalent Y(1), and three equivalent Y(2) atoms.
Y5Ru2 crystallizes in the monoclinic C2/c space group. There are three inequivalent Y sites. In the first Y site, Y(1) is bonded in a 2-coordinate geometry to three equivalent Ru(1) atoms. There are a spread of Y(1)-Ru(1) bond distances ranging from 2.75-3.41 Å. In the second Y site, Y(3) is bonded to four equivalent Ru(1) atoms to form distorted edge-sharing YRu4 tetrahedra. There are two shorter (2.90 Å) and two longer (2.94 Å) Y(3)-Ru(1) bond lengths. In the third Y site, Y(2) is bonded in a 3-coordinate geometry to three equivalent Ru(1) atoms. There are a spread of Y(2)-Ru(1) bond distances ranging from 2.85-3.06 Å. Ru(1) is bonded in a 8-coordinate geometry to two equivalent Y(3), three equivalent Y(1), and three equivalent Y(2) atoms.
