Tm3Ru2 crystallizes in the hexagonal P6_3/m space group. Tm(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 Tm(1) and two equivalent Ru(2) atoms. In the second Ru site, Ru(1) is bonded in a 9-coordinate geometry to nine equivalent Tm(1) atoms.
Tm3Ru2 crystallizes in the hexagonal P6_3/m space group. Tm(1) is bonded in a 5-coordinate geometry to two equivalent Ru(2) and three equivalent Ru(1) atoms. Both Tm(1)-Ru(2) bond lengths are 2.90 Å. There is one shorter (2.94 Å) and two longer (3.08 Å) Tm(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 Tm(1) and two equivalent Ru(2) atoms. Both Ru(2)-Ru(2) bond lengths are 2.33 Å. In the second Ru site, Ru(1) is bonded in a 9-coordinate geometry to nine equivalent Tm(1) atoms.
