Cd Cd Cu Cu Cu
Cu3Cd2 is Indium-like structured and crystallizes in the triclinic P1 space group. The structure is zero-dimensional and consists of one Cu3Cd2 cluster. There are three inequivalent Cu sites. In the first Cu site, Cu(1) is bonded in a single-bond geometry to one Cd(1) atom. The Cu(1)-Cd(1) bond length is 1.09 Å. In the second Cu site, Cu(2) is bonded in a 2-coordinate geometry to one Cd(1) and one Cd(2) atom. The Cu(2)-Cd(1) bond length is 2.28 Å. The Cu(2)-Cd(2) bond length is 1.68 Å. In the third Cu site, Cu(3) is bonded in a 1-coordinate geometry to one Cd(1) atom. The Cu(3)-Cd(1) bond length is 1.68 Å. There are two inequivalent Cd sites. In the first Cd site, Cd(1) is bonded in a 2-coordinate geometry to one Cu(1), one Cu(2), and one Cu(3) atom. In the second Cd site, Cd(2) is bonded in a 1-coordinate geometry to one Cu(2) atom.
