The crystal structure described by Pu is beta Plutonium structured and crystallizes in the monoclinic C2/m space group. There are seven inequivalent Pu sites. In the first Pu site, Pu(1) is bonded in a cuboctahedral geometry to two equivalent Pu(3), two equivalent Pu(4), four equivalent Pu(6), and four equivalent Pu(7) atoms. In the second Pu site, Pu(2) is bonded in a 4-coordinate geometry to two equivalent Pu(3), two equivalent Pu(4), two equivalent Pu(5), two equivalent Pu(7), and four equivalent Pu(6) atoms. In the third Pu site, Pu(3) is bonded in a 14-coordinate geometry to one Pu(1), one Pu(3), one Pu(4), one Pu(5), two equivalent Pu(2), four equivalent Pu(6), and four equivalent Pu(7) atoms. In the fourth Pu site, Pu(4) is bonded in a 12-coordinate geometry to one Pu(1), one Pu(3), two equivalent Pu(2), two equivalent Pu(5), two equivalent Pu(7), and four equivalent Pu(6) atoms. In the fifth Pu site, Pu(5) is bonded in a 12-coordinate geometry to one Pu(3), one Pu(5), two equivalent Pu(2), two equivalent Pu(4), two equivalent Pu(7), and four equivalent Pu(6) atoms. In the sixth Pu site, Pu(6) is bonded in a 14-coordinate geometry to one Pu(1), two equivalent Pu(2), two equivalent Pu(3), two equivalent Pu(4), two equivalent Pu(5), two equivalent Pu(6), and three equivalent Pu(7) atoms. In the seventh Pu site, Pu(7) is bonded in a 2-coordinate geometry to one Pu(1), one Pu(2), one Pu(4), one Pu(5), one Pu(7), two equivalent Pu(3), and three equivalent Pu(6) atoms. is represented by the CIF file [CIF]
