Eu Eu Lu Sc
LuEu2Sc is Cyanogen Chloride-like structured and crystallizes in the trigonal R3m space group. The structure is zero-dimensional and consists of three LuEu2Sc clusters. Lu(1) is bonded in a linear geometry to one Eu(1) and one Eu(2) atom. The Lu(1)-Eu(1) bond length is 0.13 Å. The Lu(1)-Eu(2) bond length is 0.13 Å. There are two inequivalent Eu sites. In the first Eu site, Eu(1) is bonded in a single-bond geometry to one Lu(1) atom. In the second Eu site, Eu(2) is bonded in a linear geometry to one Lu(1) and one Sc(1) atom. The Eu(2)-Sc(1) bond length is 0.13 Å. Sc(1) is bonded in a single-bond geometry to one Eu(2) atom.
