RhTl2 crystallizes in the triclinic P1 space group. Rh(1) is bonded in a 8-coordinate geometry to four equivalent Rh(1), two equivalent Tl(1), and two equivalent Tl(2) atoms. All Rh(1)-Rh(1) bond lengths are 3.22 Å. There is one shorter (3.43 Å) and one longer (3.53 Å) Rh(1)-Tl(1) bond length. There is one shorter (3.62 Å) and one longer (3.63 Å) Rh(1)-Tl(2) bond length. There are two inequivalent Tl sites. In the first Tl site, Tl(1) is bonded in a distorted single-bond geometry to two equivalent Rh(1) and one Tl(2) atom. The Tl(1)-Tl(2) bond length is 1.02 Å. In the second Tl site, Tl(2) is bonded in a distorted single-bond geometry to two equivalent Rh(1) and one Tl(1) atom.
