Al Tl Rh Rh
Rh2TlAl crystallizes in the triclinic P1 space group. There are two inequivalent Rh sites. In the first Rh site, Rh(1) is bonded in a 8-coordinate geometry to two equivalent Rh(1), two equivalent Rh(2), two equivalent Tl(1), and two equivalent Al(1) atoms. Both Rh(1)-Rh(1) bond lengths are 3.10 Å. There is one shorter (1.67 Å) and one longer (2.89 Å) Rh(1)-Rh(2) bond length. There is one shorter (3.01 Å) and one longer (3.16 Å) Rh(1)-Tl(1) bond length. There is one shorter (2.82 Å) and one longer (2.98 Å) Rh(1)-Al(1) bond length. In the second Rh site, Rh(2) is bonded in a 8-coordinate geometry to two equivalent Rh(1), two equivalent Rh(2), two equivalent Tl(1), and two equivalent Al(1) atoms. Both Rh(2)-Rh(2) bond lengths are 3.10 Å. There is one shorter (2.82 Å) and one longer (2.98 Å) Rh(2)-Tl(1) bond length. There is one shorter (3.01 Å) and one longer (3.16 Å) Rh(2)-Al(1) bond length. Tl(1) is bonded in a distorted single-bond geometry to two equivalent Rh(1), two equivalent Rh(2), and one Al(1) atom. The Tl(1)-Al(1) bond length is 0.33 Å. Al(1) is bonded in a distorted single-bond geometry to two equivalent Rh(1), two equivalent Rh(2), and one Tl(1) atom.
