Na La Mg Mg
NaMg2La is Copper structured and crystallizes in the triclinic P1 space group. The structure is zero-dimensional and consists of one NaMg2La cluster. Na(1) is bonded in a single-bond geometry to one La(1) atom. The Na(1)-La(1) bond length is 0.20 Å. There are two inequivalent Mg sites. In the first Mg site, Mg(1) is bonded in a distorted single-bond geometry to one La(1) atom. The Mg(1)-La(1) bond length is 1.79 Å. In the second Mg site, Mg(2) is bonded in a single-bond geometry to one La(1) atom. The Mg(2)-La(1) bond length is 1.62 Å. La(1) is bonded in a distorted single-bond geometry to one Na(1), one Mg(1), and one Mg(2) atom.
