The material structure described by Co crystallizes in the cubic Fd-3m space group. There are two inequivalent Co sites. In the first Co site, Co(1) is bonded in a 16-coordinate geometry to four equivalent Co(1) and twelve equivalent Co(2) atoms. In the second Co site, Co(2) is bonded to six equivalent Co(1) and six equivalent Co(2) atoms to form a mixture of face, edge, and corner-sharing CoCo12 cuboctahedra. is represented by the Crystallographic Information File (CIF) [CIF]
