RuTlTlBi crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two RuTl clusters and two TlBi clusters. In each RuTl cluster, Ru(1) is bonded in a distorted single-bond geometry to one Tl(1) atom. The Ru(1)-Tl(1) bond length is 2.18 Å. Tl(1) is bonded in a distorted single-bond geometry to one Ru(1) atom. In each TlBi cluster, Tl(2) is bonded in a 1-coordinate geometry to one Bi(1) atom. The Tl(2)-Bi(1) bond length is 1.57 Å. Bi(1) is bonded in a 1-coordinate geometry to one Tl(2) atom.
