La Zn Zn B
LaZn2B crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two LaZn2B clusters. La(1) is bonded in a single-bond geometry to one Zn(1), one Zn(2), and one B(1) atom. The La(1)-Zn(1) bond length is 3.01 Å. The La(1)-Zn(2) bond length is 0.14 Å. The La(1)-B(1) bond length is 1.79 Å. There are two inequivalent Zn sites. In the first Zn site, Zn(1) is bonded in a 2-coordinate geometry to one La(1) and one B(1) atom. The Zn(1)-B(1) bond length is 2.73 Å. In the second Zn site, Zn(2) is bonded in a single-bond geometry to one La(1) and one B(1) atom. The Zn(2)-B(1) bond length is 1.78 Å. B(1) is bonded in a 2-coordinate geometry to one La(1), one Zn(1), and one Zn(2) atom.
