SrLaMgLa is Cubic alpha N2-derived structured and crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two MgLa clusters and two SrLa clusters. In each MgLa cluster, Mg(1) is bonded in a single-bond geometry to one La(2) atom. The Mg(1)-La(2) bond length is 1.33 Å. La(2) is bonded in a single-bond geometry to one Mg(1) atom. In each SrLa cluster, Sr(1) is bonded in a single-bond geometry to one La(1) atom. The Sr(1)-La(1) bond length is 0.47 Å. La(1) is bonded in a single-bond geometry to one Sr(1) atom.
