Cu C
CuC is alpha carbon monoxide-like structured and crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two copper;methane molecules. Cu(1) is bonded in a single-bond geometry to one C(1) atom. The Cu(1)-C(1) bond length is 0.37 Å. C(1) is bonded in a single-bond geometry to one Cu(1) atom.
