Materials Data on La(AlGa)2 by Materials Project

LaAl2Ga2 crystallizes in the tetragonal I4/mmm space group. The structure is three-dimensional. La is bonded in a 8-coordinate geometry to eight equivalent Ga and eight equivalent Al atoms. All La–Ga bond lengths are 3.29 Å. All La–Al bond lengths are 3.52 Å. Ga is bonded in a 9-coordinate geometry to four equivalent La, one Ga, and four equivalent Al atoms. The Ga–Ga bond length is 2.56 Å. All Ga–Al bond lengths are 2.63 Å. Al is bonded to four equivalent La and four equivalent Ga atoms to form a mixture of distorted corner, edge, and face-sharing AlLa4Ga4 tetrahedra.
