RuTl2 crystallizes in the triclinic P1 space group. There are two inequivalent Ru sites. In the first Ru site, Ru(1) is bonded in a 3-coordinate geometry to one Ru(2), one Tl(1), one Tl(2), and one Tl(3) atom. The Ru(1)-Ru(2) bond length is 0.45 Å. The Ru(1)-Tl(1) bond length is 2.23 Å. The Ru(1)-Tl(2) bond length is 2.58 Å. The Ru(1)-Tl(3) bond length is 2.77 Å. In the second Ru site, Ru(2) is bonded in a 2-coordinate geometry to one Ru(1), one Tl(4), and two equivalent Tl(3) atoms. The Ru(2)-Tl(4) bond length is 2.63 Å. There is one shorter (2.91 Å) and one longer (3.38 Å) Ru(2)-Tl(3) bond length. There are four inequivalent Tl sites. In the first Tl site, Tl(1) is bonded in a 2-coordinate geometry to one Ru(1), one Tl(3), and one Tl(4) atom. The Tl(1)-Tl(3) bond length is 1.82 Å. The Tl(1)-Tl(4) bond length is 2.19 Å. In the second Tl site, Tl(2) is bonded in a 2-coordinate geometry to one Ru(1), one Tl(3), and one Tl(4) atom. The Tl(2)-Tl(3) bond length is 2.19 Å. The Tl(2)-Tl(4) bond length is 1.82 Å. In the third Tl site, Tl(3) is bonded in a 6-coordinate geometry to one Ru(1), two equivalent Ru(2), one Tl(1), one Tl(2), and one Tl(4) atom. The Tl(3)-Tl(4) bond length is 2.03 Å. In the fourth Tl site, Tl(4) is bonded in a 4-coordinate geometry to one Ru(2), one Tl(1), one Tl(2), and one Tl(3) atom.
