Pu is alpha Pu structured and crystallizes in the monoclinic P2_1/m space group. There are eight inequivalent Pu sites. In the first Pu site, Pu(1) is bonded in a 4-coordinate geometry to one Pu(3) and three equivalent Pu(6) atoms. In the second Pu site, Pu(2) is bonded in a 5-coordinate geometry to one Pu(4), one Pu(7), one Pu(8), and two equivalent Pu(5) atoms. In the third Pu site, Pu(3) is bonded in a 4-coordinate geometry to one Pu(1), one Pu(6), and two equivalent Pu(8) atoms. In the fourth Pu site, Pu(4) is bonded to one Pu(2), one Pu(5), and two equivalent Pu(7) atoms to form corner-sharing PuPu4 trigonal pyramids. In the fifth Pu site, Pu(5) is bonded in a distorted trigonal planar geometry to one Pu(4) and two equivalent Pu(2) atoms. In the sixth Pu site, Pu(6) is bonded in a 4-coordinate geometry to one Pu(3) and three equivalent Pu(1) atoms. In the seventh Pu site, Pu(7) is bonded in a 4-coordinate geometry to one Pu(2), one Pu(8), and two equivalent Pu(4) atoms. In the eighth Pu site, Pu(8) is bonded to one Pu(2), one Pu(7), and two equivalent Pu(3) atoms to form distorted corner-sharing PuPu4 trigonal pyramids.
