SmB2 is hexagonal omega structure structured and crystallizes in the hexagonal P6/mmm space group. Sm(1) is bonded to twelve equivalent B(1) atoms to form a mixture of face and edge-sharing SmB12 cuboctahedra. B(1) is bonded in a 9-coordinate geometry to six equivalent Sm(1) and three equivalent B(1) atoms.
