Sc5Ru3 crystallizes in the hexagonal P6_3/mcm space group. There are two inequivalent Sc sites. In the first Sc site, Sc(1) is bonded in a 6-coordinate geometry to six equivalent Ru(1) atoms. In the second Sc site, Sc(2) is bonded in a 5-coordinate geometry to five equivalent Ru(1) atoms. Ru(1) is bonded in a 9-coordinate geometry to four equivalent Sc(1) and five equivalent Sc(2) atoms.
Sc5Ru3 crystallizes in the hexagonal P6_3/mcm space group. There are two inequivalent Sc sites. In the first Sc site, Sc(1) is bonded in a 6-coordinate geometry to six equivalent Ru(1) atoms. All Sc(1)-Ru(1) bond lengths are 2.79 Å. In the second Sc site, Sc(2) is bonded in a 5-coordinate geometry to five equivalent Ru(1) atoms. There are a spread of Sc(2)-Ru(1) bond distances ranging from 2.65-3.14 Å. Ru(1) is bonded in a 9-coordinate geometry to four equivalent Sc(1) and five equivalent Sc(2) atoms.
