RuLiVHg is Halite, Rock Salt structured and crystallizes in the trigonal R3m space group. The structure is zero-dimensional and consists of three RuLi clusters and three VHg 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 1.57 Å. Ru(1) is bonded in a single-bond geometry to one Li(1) atom. In each VHg cluster, V(1) is bonded in a single-bond geometry to one Hg(1) atom. The V(1)-Hg(1) bond length is 1.57 Å. Hg(1) is bonded in a single-bond geometry to one V(1) atom.
