Tl Tl Ag Rh
RhAgTl2 crystallizes in the monoclinic Cm space group. Rh(1) is bonded in a single-bond geometry to one Ag(1) and one Tl(1) atom. The Rh(1)-Ag(1) bond length is 3.16 Å. The Rh(1)-Tl(1) bond length is 0.12 Å. Ag(1) is bonded in a distorted linear geometry to one Rh(1), six equivalent Ag(1), and one Tl(2) atom. All Ag(1)-Ag(1) bond lengths are 3.28 Å. The Ag(1)-Tl(2) bond length is 3.28 Å. There are two inequivalent Tl sites. In the first Tl site, Tl(1) is bonded in a single-bond geometry to one Rh(1) and one Tl(2) atom. The Tl(1)-Tl(2) bond length is 2.74 Å. In the second Tl site, Tl(2) is bonded to one Ag(1), one Tl(1), and six equivalent Tl(2) atoms to form a mixture of distorted corner and edge-sharing TlTl7Ag hexagonal bipyramids. All Tl(2)-Tl(2) bond lengths are 3.28 Å.
