The material structure described by SmCo5 crystallizes in the hexagonal P6/mmm space group. Sm(1) is bonded in a 18-coordinate geometry to six equivalent Co(1) and twelve equivalent Co(2) atoms. There are two inequivalent Co sites. In the first Co site, Co(1) is bonded in a 9-coordinate geometry to three equivalent Sm(1) and six equivalent Co(2) atoms. In the second Co site, Co(2) is bonded to four equivalent Sm(1), four equivalent Co(1), and four equivalent Co(2) atoms to form a mixture of face, corner, and edge-sharing CoSm4Co8 cuboctahedra. is represented by the CIF file [CIF]
