LaMnZn2 crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two LaMnZn2 clusters. La(1) is bonded in a single-bond geometry to one Mn(1) and one Zn(1) atom. The La(1)-Mn(1) bond length is 1.74 Å. The La(1)-Zn(1) bond length is 0.15 Å. Mn(1) is bonded in a 1-coordinate geometry to one La(1) and one Zn(2) atom. The Mn(1)-Zn(2) bond length is 2.89 Å. There are two inequivalent Zn sites. In the first Zn site, Zn(1) is bonded in a single-bond geometry to one La(1) atom. In the second Zn site, Zn(2) is bonded in a single-bond geometry to one Mn(1) atom.
