Tl Tl Tl Rh
RhTl3 crystallizes in the monoclinic Cm space group. Rh(1) is bonded in a 2-coordinate geometry to one Tl(1) and one Tl(3) atom. The Rh(1)-Tl(1) bond length is 2.79 Å. The Rh(1)-Tl(3) bond length is 2.95 Å. There are three inequivalent Tl sites. In the first Tl site, Tl(1) is bonded in a 1-coordinate geometry to one Rh(1) and three equivalent Tl(2) atoms. There is one shorter (2.72 Å) and two longer (3.25 Å) Tl(1)-Tl(2) bond lengths. In the second Tl site, Tl(2) is bonded in a 10-coordinate geometry to three equivalent Tl(1), three equivalent Tl(3), and four equivalent Tl(2) atoms. There is one shorter (2.72 Å) and two longer (3.25 Å) Tl(2)-Tl(3) bond lengths. All Tl(2)-Tl(2) bond lengths are 3.29 Å. In the third Tl site, Tl(3) is bonded in a 1-coordinate geometry to one Rh(1) and three equivalent Tl(2) atoms.
