OsCuGe is Cyanogen Chloride-like structured and crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two OsCuGe clusters. Os(1) is bonded in a linear geometry to one Cu(1) and one Ge(1) atom. The Os(1)-Cu(1) bond length is 1.24 Å. The Os(1)-Ge(1) bond length is 0.32 Å. Cu(1) is bonded in a single-bond geometry to one Os(1) atom. Ge(1) is bonded in a single-bond geometry to one Os(1) atom.
