Li Li Tl Ru
RuLiLiTl crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two lithium;thallium molecules and two RuLi clusters. In each RuLi cluster, Li(1) is bonded in a single-bond geometry to one Ru(1) atom. The Li(1)-Ru(1) bond length is 1.11 Å. Ru(1) is bonded in a distorted single-bond geometry to one Li(1) atom.
