Al Cu Cu Bi
CuAlCuBi is alpha carbon monoxide-like structured and crystallizes in the triclinic P1 space group. The structure is zero-dimensional and consists of one aluminium--copper (1/1) molecule and one CuBi cluster. In the CuBi cluster, Cu(2) is bonded in a single-bond geometry to one Bi(1) atom. The Cu(2)-Bi(1) bond length is 0.22 Å. Bi(1) is bonded in a single-bond geometry to one Cu(2) atom.
