Materials Data on SmAlGa by Materials Project
SmGaAl is hexagonal omega structure-derived structured and crystallizes in the hexagonal P-6m2 space group. The structure is three-dimensional. Sm is bonded to six equivalent Ga and six equivalent Al atoms to form a mixture of edge and face-sharing SmAl6Ga6 cuboctahedra. All Sm–Ga bond lengths are 3.21 Å. All Sm–Al bond lengths are 3.21 Å. Ga is bonded in a 3-coordinate geometry to six equivalent Sm and three equivalent Al atoms. All Ga–Al bond lengths are 2.55 Å. Al is bonded in a 3-coordinate geometry to six equivalent Sm and three equivalent Ga atoms.
