RuCoTl2 crystallizes in the triclinic P1 space group. Ru(1) is bonded in a single-bond geometry to one Tl(1) and three equivalent Tl(2) atoms. The Ru(1)-Tl(1) bond length is 1.22 Å. There are a spread of Ru(1)-Tl(2) bond distances ranging from 2.33-3.34 Å. Co(1) is bonded in a single-bond geometry to one Tl(1) and two equivalent Tl(2) atoms. The Co(1)-Tl(1) bond length is 0.53 Å. There is one shorter (2.10 Å) and one longer (3.40 Å) Co(1)-Tl(2) bond length. There are two inequivalent Tl sites. In the first Tl site, Tl(1) is bonded in a linear geometry to one Ru(1), one Co(1), and one Tl(2) atom. The Tl(1)-Tl(2) bond length is 2.09 Å. In the second Tl site, Tl(2) is bonded in a 8-coordinate geometry to three equivalent Ru(1), two equivalent Co(1), one Tl(1), and two equivalent Tl(2) atoms. Both Tl(2)-Tl(2) bond lengths are 3.07 Å.
