Co22B6Sb crystallizes in the cubic Fm-3m space group. There are three inequivalent Co sites. In the first Co site, Co(1) is bonded in a distorted tetrahedral geometry to four equivalent Co(2) atoms. In the second Co site, Co(2) is bonded in a 3-coordinate geometry to one Co(1) and three equivalent B(1) atoms. In the third Co site, Co(3) is bonded in a 2-coordinate geometry to two equivalent B(1) and one Sb(1) atom. B(1) is bonded in a 8-coordinate geometry to four equivalent Co(2) and four equivalent Co(3) atoms. Sb(1) is bonded in a cuboctahedral geometry to twelve equivalent Co(3) atoms.
