La La Zn Zn
LaZn crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two LaZn clusters. There are two inequivalent La sites. In the first La site, La(1) is bonded in an L-shaped geometry to two equivalent Zn(1) atoms. Both La(1)-Zn(1) bond lengths are 1.85 Å. In the second La site, La(2) is bonded in a distorted L-shaped geometry to two equivalent Zn(1) atoms. Both La(2)-Zn(1) bond lengths are 1.93 Å. Zn(1) is bonded in an L-shaped geometry to one La(1) and one La(2) atom.
