Tl Tl Sb Rh
RhTl2Sb crystallizes in the monoclinic Cm space group. Rh(1) is bonded in a 2-coordinate geometry to one Tl(1) and one Tl(2) atom. The Rh(1)-Tl(1) bond length is 2.54 Å. The Rh(1)-Tl(2) bond length is 2.59 Å. There are two inequivalent Tl sites. In the first Tl site, Tl(1) is bonded in a 1-coordinate geometry to one Rh(1) and three equivalent Sb(1) atoms. There is one shorter (3.11 Å) and two longer (3.51 Å) Tl(1)-Sb(1) bond lengths. In the second Tl site, Tl(2) is bonded in a 1-coordinate geometry to one Rh(1) and three equivalent Sb(1) atoms. There is one shorter (3.11 Å) and two longer (3.51 Å) Tl(2)-Sb(1) bond lengths. Sb(1) is bonded in a distorted bent 120 degrees geometry to three equivalent Tl(1), three equivalent Tl(2), and four equivalent Sb(1) atoms. All Sb(1)-Sb(1) bond lengths are 3.25 Å.
