CuC6 crystallizes in the orthorhombic Cmmm space group. Cu(1) is bonded in an octahedral geometry to two equivalent C(1) and four equivalent C(2) atoms. There are two inequivalent C sites. In the first C site, C(1) is bonded in a distorted linear geometry to one Cu(1) and one C(1) atom. In the second C site, C(2) is bonded in a distorted trigonal planar geometry to one Cu(1) and two equivalent C(2) atoms.
CuC6 crystallizes in the orthorhombic Cmmm space group. Cu(1) is bonded in an octahedral geometry to two equivalent C(1) and four equivalent C(2) atoms. Both Cu(1)-C(1) bond lengths are 1.86 Å. All Cu(1)-C(2) bond lengths are 2.39 Å. There are two inequivalent C sites. In the first C site, C(1) is bonded in a distorted linear geometry to one Cu(1) and one C(1) atom. The C(1)-C(1) bond length is 1.25 Å. In the second C site, C(2) is bonded in a distorted trigonal planar geometry to one Cu(1) and two equivalent C(2) atoms. There is one shorter (1.25 Å) and one longer (1.34 Å) C(2)-C(2) bond length.
