SmCo3Ni2 crystallizes in the hexagonal P6/mmm space group. Sm(1) is bonded in a distorted hexagonal planar geometry to twelve equivalent Co(1) and six equivalent Ni(1) atoms. Co(1) is bonded to four equivalent Sm(1), four equivalent Co(1), and four equivalent Ni(1) atoms to form a mixture of corner, edge, and face-sharing CoSm4Co4Ni4 cuboctahedra. Ni(1) is bonded in a 9-coordinate geometry to three equivalent Sm(1) and six equivalent Co(1) atoms.
