Lu3Ru2 crystallizes in the hexagonal P6_3/m space group. Lu(1) is bonded in a 5-coordinate geometry to two equivalent Ru(2) and three equivalent Ru(1) atoms. There are two inequivalent Ru sites. In the first Ru site, Ru(2) is bonded in a body-centered cubic geometry to six equivalent Lu(1) and two equivalent Ru(2) atoms. In the second Ru site, Ru(1) is bonded in a 9-coordinate geometry to nine equivalent Lu(1) atoms.
Lu3Ru2 crystallizes in the hexagonal P6_3/m space group. Lu(1) is bonded in a 5-coordinate geometry to two equivalent Ru(2) and three equivalent Ru(1) atoms. Both Lu(1)-Ru(2) bond lengths are 2.88 Å. There is one shorter (2.95 Å) and two longer (3.05 Å) Lu(1)-Ru(1) bond lengths. There are two inequivalent Ru sites. In the first Ru site, Ru(2) is bonded in a body-centered cubic geometry to six equivalent Lu(1) and two equivalent Ru(2) atoms. Both Ru(2)-Ru(2) bond lengths are 2.32 Å. In the second Ru site, Ru(1) is bonded in a 9-coordinate geometry to nine equivalent Lu(1) atoms.
