LuYbTm2 is Cyanogen Chloride-like structured and crystallizes in the trigonal R3m space group. The structure is zero-dimensional and consists of three LuYbTm2 clusters. Lu(1) is bonded in a linear geometry to one Tm(1) and one Tm(2) atom. The Lu(1)-Tm(1) bond length is 0.24 Å. The Lu(1)-Tm(2) bond length is 0.24 Å. Yb(1) is bonded in a single-bond geometry to one Tm(1) atom. The Yb(1)-Tm(1) bond length is 0.24 Å. There are two inequivalent Tm sites. In the first Tm site, Tm(1) is bonded in a linear geometry to one Lu(1) and one Yb(1) atom. In the second Tm site, Tm(2) is bonded in a single-bond geometry to one Lu(1) atom.
