Ru2GeBr is Cyanogen Chloride-like structured and crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two Ru2GeBr clusters. There are two inequivalent Ru sites. In the first Ru site, Ru(1) is bonded in a single-bond geometry to one Br(1) atom. The Ru(1)-Br(1) bond length is 1.30 Å. In the second Ru site, Ru(2) is bonded in a single-bond geometry to one Ge(1) atom. The Ru(2)-Ge(1) bond length is 0.70 Å. Ge(1) is bonded in a linear geometry to one Ru(2) and one Br(1) atom. The Ge(1)-Br(1) bond length is 0.60 Å. Br(1) is bonded in a linear geometry to one Ru(1) and one Ge(1) atom.
