La Mg Ga Ga
MgLaGa2 crystallizes in the triclinic P1 space group. The structure is zero-dimensional and consists of one MgLaGa2 cluster. Mg(1) is bonded in a 2-coordinate geometry to one Ga(1) and one Ga(2) atom. The Mg(1)-Ga(1) bond length is 1.97 Å. The Mg(1)-Ga(2) bond length is 2.02 Å. La(1) is bonded in a distorted single-bond geometry to one Ga(1) atom. The La(1)-Ga(1) bond length is 2.01 Å. There are two inequivalent Ga sites. In the first Ga site, Ga(1) is bonded in a 2-coordinate geometry to one Mg(1) and one La(1) atom. In the second Ga site, Ga(2) is bonded in a 1-coordinate geometry to one Mg(1) atom.
