Tl Tl Ag Rh
RhAgTl2 crystallizes in the monoclinic Cm space group. Rh(1) is bonded in a single-bond geometry to one Tl(1) and one Tl(2) atom. The Rh(1)-Tl(1) bond length is 3.45 Å. The Rh(1)-Tl(2) bond length is 1.31 Å. Ag(1) is bonded in a 4-coordinate geometry to one Tl(1) and three equivalent Tl(2) atoms. The Ag(1)-Tl(1) bond length is 2.63 Å. There is one shorter (2.20 Å) and two longer (2.76 Å) Ag(1)-Tl(2) bond lengths. There are two inequivalent Tl sites. In the first Tl site, Tl(1) is bonded in a 6-coordinate geometry to one Rh(1), one Ag(1), and four equivalent Tl(1) atoms. All Tl(1)-Tl(1) bond lengths are 3.26 Å. In the second Tl site, Tl(2) is bonded in a distorted single-bond geometry to one Rh(1) and three equivalent Ag(1) atoms.
