FeAu2Cd is Cyanogen Chloride-like structured and crystallizes in the monoclinic Pm space group. The structure is zero-dimensional and consists of one FeAu2Cd cluster. Fe(1) is bonded in a linear geometry to one Au(2) and one Cd(1) atom. The Fe(1)-Au(2) bond length is 1.23 Å. The Fe(1)-Cd(1) bond length is 0.26 Å. There are two inequivalent Au sites. In the first Au site, Au(1) is bonded in a single-bond geometry to one Cd(1) atom. The Au(1)-Cd(1) bond length is 1.48 Å. In the second Au site, Au(2) is bonded in a single-bond geometry to one Fe(1) atom. Cd(1) is bonded in a linear geometry to one Fe(1) and one Au(1) atom.
