SmGaAl is hexagonal omega structure-derived structured and crystallizes in the hexagonal P-6m2 space group. Sm(1) is bonded to six equivalent Ga(1) and six equivalent Al(1) atoms to form a mixture of edge and face-sharing SmAl6Ga6 cuboctahedra. Ga(1) is bonded in a 9-coordinate geometry to six equivalent Sm(1) and three equivalent Al(1) atoms. Al(1) is bonded in a distorted trigonal planar geometry to six equivalent Sm(1) and three equivalent Ga(1) atoms.
