Rh2CoTl crystallizes in the monoclinic Cm space group. There are two inequivalent Rh sites. In the first Rh site, Rh(1) is bonded in a distorted single-bond geometry to four equivalent Co(1) and one Tl(1) atom. There are a spread of Rh(1)-Co(1) bond distances ranging from 1.99-2.92 Å. The Rh(1)-Tl(1) bond length is 1.01 Å. In the second Rh site, Rh(2) is bonded in a 4-coordinate geometry to one Co(1) and three equivalent Tl(1) atoms. The Rh(2)-Co(1) bond length is 2.53 Å. There is one shorter (2.37 Å) and two longer (2.80 Å) Rh(2)-Tl(1) bond lengths. Co(1) is bonded in a 5-coordinate geometry to one Rh(2) and four equivalent Rh(1) atoms. Tl(1) is bonded in a distorted single-bond geometry to one Rh(1) and three equivalent Rh(2) atoms.
