La2Sc is Hg_xSn structured and crystallizes in the triclinic P-1 space group. The structure is zero-dimensional and consists of one La2Sc cluster. There are two inequivalent La sites. In the first La site, La(1) is bonded in a 2-coordinate geometry to two equivalent Sc(1) atoms. There is one shorter (1.45 Å) and one longer (1.61 Å) La(1)-Sc(1) bond length. In the second La site, La(2) is bonded in a 1-coordinate geometry to one Sc(1) atom. The La(2)-Sc(1) bond length is 1.96 Å. Sc(1) is bonded in a 4-coordinate geometry to one La(2), two equivalent La(1), and one Sc(1) atom. The Sc(1)-Sc(1) bond length is 1.29 Å.
