The crystal structure described by Sm3Zn is beta Cu3Ti-like structured and crystallizes in the hexagonal P6_3/mmc space group. Sm(1) is bonded in a 12-coordinate geometry to eight equivalent Sm(1) and four equivalent Zn(1) atoms. Zn(1) is bonded to twelve equivalent Sm(1) atoms to form a mixture of face and corner-sharing ZnSm12 cuboctahedra. is represented by the CIF file [CIF]
