La Be Ru Ru
BeLaRu2 is Cyanogen Chloride-like structured and crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two BeLaRu2 clusters. Be(1) is bonded in a linear geometry to one La(1) and one Ru(2) atom. The Be(1)-La(1) bond length is 0.36 Å. The Be(1)-Ru(2) bond length is 0.61 Å. La(1) is bonded in a linear geometry to one Be(1) and one Ru(1) atom. The La(1)-Ru(1) bond length is 0.61 Å. There are two inequivalent Ru sites. In the first Ru site, Ru(1) is bonded in a single-bond geometry to one La(1) atom. In the second Ru site, Ru(2) is bonded in a single-bond geometry to one Be(1) atom.
