Materials Data on SmGa2 by Materials Project
SmGa2 is hexagonal omega structure structured and crystallizes in the hexagonal P6/mmm space group. The structure is three-dimensional. Sm is bonded to twelve equivalent Ga atoms to form a mixture of edge and face-sharing SmGa12 cuboctahedra. All Sm–Ga bond lengths are 3.24 Å. Ga is bonded in a 9-coordinate geometry to six equivalent Sm and three equivalent Ga atoms. All Ga–Ga bond lengths are 2.46 Å.
