Bi C
CBi is Tungsten Carbide structured and crystallizes in the triclinic P1 space group. The structure is zero-dimensional and consists of one CBi cluster. C(1) is bonded in a distorted single-bond geometry to one Bi(1) atom. The C(1)-Bi(1) bond length is 1.39 Å. Bi(1) is bonded in a distorted single-bond geometry to one C(1) atom.
