The crystal structure described by Sm12Co6Sn crystallizes in the cubic Im-3 space group. Sm(1) is bonded in a 3-coordinate geometry to three equivalent Co(1) and one Sn(1) atom. Co(1) is bonded in a 7-coordinate geometry to six equivalent Sm(1) and one Co(1) atom. Sn(1) is bonded in a cuboctahedral geometry to twelve equivalent Sm(1) atoms. is represented by the CIF file [CIF]
