The material structure described by Co5(SnSb)2 crystallizes in the hexagonal P-6m2 space group. There are three inequivalent Co sites. In the first Co site, Co(1) is bonded in a 11-coordinate geometry to one Co(1), one Co(2), three equivalent Co(3), three equivalent Sn(1), and three equivalent Sb(1) atoms. In the second Co site, Co(2) is bonded in a body-centered cubic geometry to one Co(1), one Co(2), three equivalent Sn(2), and three equivalent Sb(1) atoms. In the third Co site, Co(3) is bonded to six equivalent Co(1), three equivalent Sn(1), and two equivalent Sb(1) atoms to form distorted face-sharing CoCo6Sn3Sb2 trigonal bipyramids. There are two inequivalent Sn sites. In the first Sn site, Sn(1) is bonded in a 9-coordinate geometry to three equivalent Co(3) and six equivalent Co(1) atoms. In the second Sn site, Sn(2) is bonded in a 6-coordinate geometry to six equivalent Co(2) atoms. Sb(1) is bonded in a 7-coordinate geometry to one Co(3), three equivalent Co(1), and three equivalent Co(2) atoms. is represented by the Crystallographic Information File (CIF) [CIF]
