The structure described by Pu2Co crystallizes in the hexagonal P-62m space group. There are two inequivalent Pu sites. In the first Pu site, Pu(1) is bonded in a 5-coordinate geometry to one Co(2) and four equivalent Co(1) atoms. In the second Pu site, Pu(2) is bonded to two equivalent Co(1) and two equivalent Co(2) atoms to form a mixture of distorted edge and corner-sharing PuCo4 tetrahedra. There are two inequivalent Co sites. In the first Co site, Co(2) is bonded in a 9-coordinate geometry to three equivalent Pu(1) and six equivalent Pu(2) atoms. In the second Co site, Co(1) is bonded in a 9-coordinate geometry to three equivalent Pu(2) and six equivalent Pu(1) atoms. is represented by the Crystallographic Information File (CIF) [CIF]
