Sc Cd Cu Cu
ScCu2Cd crystallizes in the monoclinic Cm space group. Sc(1) is bonded in a distorted single-bond geometry to three equivalent Cu(1) and one Cd(1) atom. There is one shorter (2.22 Å) and two longer (2.81 Å) Sc(1)-Cu(1) bond lengths. The Sc(1)-Cd(1) bond length is 0.83 Å. There are two inequivalent Cu sites. In the first Cu site, Cu(1) is bonded in a 4-coordinate geometry to three equivalent Sc(1) and one Cu(2) atom. The Cu(1)-Cu(2) bond length is 1.70 Å. In the second Cu site, Cu(2) is bonded in a 2-coordinate geometry to one Cu(1) and one Cd(1) atom. The Cu(2)-Cd(1) bond length is 2.83 Å. Cd(1) is bonded in a single-bond geometry to one Sc(1) and one Cu(2) atom.
