The compound described by Pu is alpha Np-like structured and crystallizes in the triclinic P-1 space group. There are two inequivalent Pu sites. In the first Pu site, Pu(1) is bonded in a 4-coordinate geometry to one Pu(1) and three equivalent Pu(2) atoms. In the second Pu site, Pu(2) is bonded in a 4-coordinate geometry to one Pu(2) and three equivalent Pu(1) atoms. is represented by the CIF file [CIF]
