The structure described by Pu6Co crystallizes in the tetragonal I4/mcm space group. There are two inequivalent Pu sites. In the first Pu site, Pu(1) is bonded in a 13-coordinate geometry to five equivalent Pu(1) and eight equivalent Pu(2) atoms. In the second Pu site, Pu(2) is bonded in a 2-coordinate geometry to four equivalent Pu(1) and two equivalent Co(1) atoms. Co(1) is bonded in a 10-coordinate geometry to eight equivalent Pu(2) and two equivalent Co(1) atoms. is represented by the Crystallographic Information File (CIF) [CIF]
