Cd Cd Cu Ag
AgCuCd2 crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two AgCuCd2 clusters. Ag(1) is bonded in a single-bond geometry to one Cd(1) and one Cd(2) atom. The Ag(1)-Cd(1) bond length is 2.13 Å. The Ag(1)-Cd(2) bond length is 0.11 Å. Cu(1) is bonded in a single-bond geometry to one Cd(1) atom. The Cu(1)-Cd(1) bond length is 1.56 Å. There are two inequivalent Cd sites. In the first Cd site, Cd(1) is bonded in a 2-coordinate geometry to one Ag(1) and one Cu(1) atom. In the second Cd site, Cd(2) is bonded in a single-bond geometry to one Ag(1) atom.
