Tl Tl Ru Cl
RuTlTlCl is beta oxygen-derived structured and crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two thallium chloride molecules and two RuTl clusters. In each RuTl cluster, Ru(1) is bonded in a single-bond geometry to one Tl(2) atom. The Ru(1)-Tl(2) bond length is 0.89 Å. Tl(2) is bonded in a single-bond geometry to one Ru(1) atom.
