SmCo2Cu3 crystallizes in the hexagonal P6/mmm space group. Sm(1) is bonded in a distorted hexagonal planar geometry to six equivalent Co(1) and twelve equivalent Cu(1) atoms. Co(1) is bonded in a 9-coordinate geometry to three equivalent Sm(1) and six equivalent Cu(1) atoms. Cu(1) is bonded to four equivalent Sm(1), four equivalent Co(1), and four equivalent Cu(1) atoms to form a mixture of edge, face, and corner-sharing CuSm4Co4Cu4 cuboctahedra.
