Ba Ba Ge Ru
Ba2RuGe is Cyanogen Chloride-like structured and crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two Ba2RuGe clusters. There are two inequivalent Ba sites. In the first Ba site, Ba(1) is bonded in a single-bond geometry to one Ge(1) atom. The Ba(1)-Ge(1) bond length is 0.69 Å. In the second Ba site, Ba(2) is bonded in a single-bond geometry to one Ru(1) atom. The Ba(2)-Ru(1) bond length is 2.82 Å. Ru(1) is bonded in a linear geometry to one Ba(2) and one Ge(1) atom. The Ru(1)-Ge(1) bond length is 2.13 Å. Ge(1) is bonded in a single-bond geometry to one Ba(1) and one Ru(1) atom.
