MgLaGe2 crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two MgLaGe2 clusters. Mg(1) is bonded in a 2-coordinate geometry to one La(1) and one Ge(1) atom. The Mg(1)-La(1) bond length is 2.59 Å. The Mg(1)-Ge(1) bond length is 2.52 Å. La(1) is bonded in a 2-coordinate geometry to one Mg(1), one Ge(1), and one Ge(2) atom. The La(1)-Ge(1) bond length is 0.99 Å. The La(1)-Ge(2) bond length is 0.99 Å. There are two inequivalent Ge sites. In the first Ge site, Ge(1) is bonded in a 2-coordinate geometry to one Mg(1), one La(1), and one Ge(2) atom. The Ge(1)-Ge(2) bond length is 0.51 Å. In the second Ge site, Ge(2) is bonded in a 2-coordinate geometry to one La(1) and one Ge(1) atom.
