COs is Tungsten Carbide structured and crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two methylidyneosmium molecules. Os(1) is bonded in a 1-coordinate geometry to one C(1) atom. The Os(1)-C(1) bond length is 1.32 Å. C(1) is bonded in a 1-coordinate geometry to one Os(1) atom.
