Ba Si Ru Ru
BaRu2Si crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two BaRu2Si clusters. Ba(1) is bonded in a distorted single-bond geometry to one Ru(1) atom. The Ba(1)-Ru(1) bond length is 2.77 Å. There are two inequivalent Ru sites. In the first Ru site, Ru(1) is bonded in a linear geometry to one Ba(1) and one Ru(2) atom. The Ru(1)-Ru(2) bond length is 1.54 Å. In the second Ru site, Ru(2) is bonded in a distorted linear geometry to one Ru(1) and one Si(1) atom. The Ru(2)-Si(1) bond length is 1.59 Å. Si(1) is bonded in a single-bond geometry to one Ru(2) atom.
