Tl Tl Cu Rh
RhCuTl2 crystallizes in the triclinic P1 space group. Rh(1) is bonded in a distorted single-bond geometry to one Cu(1), one Tl(1), and two equivalent Tl(2) atoms. The Rh(1)-Cu(1) bond length is 1.02 Å. The Rh(1)-Tl(1) bond length is 2.42 Å. There is one shorter (2.57 Å) and one longer (3.21 Å) Rh(1)-Tl(2) bond length. Cu(1) is bonded in a distorted single-bond geometry to one Rh(1) and two equivalent Tl(2) atoms. There is one shorter (2.42 Å) and one longer (3.10 Å) Cu(1)-Tl(2) bond length. 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 two equivalent Tl(2) atoms. There is one shorter (2.25 Å) and one longer (2.48 Å) Tl(1)-Tl(2) bond length. In the second Tl site, Tl(2) is bonded in a 6-coordinate geometry to two equivalent Rh(1), two equivalent Cu(1), and two equivalent Tl(1) atoms.
