Ca Al Co
CaCoAl is Hg_xSn structured and crystallizes in the triclinic P1 space group. The structure is zero-dimensional and consists of one CaCoAl cluster. Ca(1) is bonded in a water-like geometry to one Co(1) and one Al(1) atom. The Ca(1)-Co(1) bond length is 0.99 Å. The Ca(1)-Al(1) bond length is 0.88 Å. Co(1) is bonded in a single-bond geometry to one Ca(1) atom. Al(1) is bonded in a single-bond geometry to one Ca(1) atom.
