Abstract

Pu is alpha Pu structured and crystallizes in the monoclinic P2_1/m space group. The structure is three-dimensional. there are eight inequivalent Pu sites. In the first Pu site, Pu is bonded in a 4-coordinate geometry to four Pu atoms. There are a spread of Pu–Pu bond distances ranging from 2.47–2.54 Å. In the second Pu site, Pu is bonded in a 5-coordinate geometry to five Pu atoms. There are a spread of Pu–Pu bond distances ranging from 2.47–2.58 Å. In the third Pu site, Pu is bonded in a 4-coordinate geometry to four Pu atoms. There are two shorter (2.51 Å) and one longer (2.52 Å) Pu–Pu bond lengths. In the fourth Pu site, Pu is bonded to four Pu atoms to form corner-sharing PuPu4 trigonal pyramids. There are two shorter (2.51 Å) and one longer (2.57 Å) Pu–Pu bond lengths. In the fifth Pu site, Pu is bonded in a distorted trigonal planar geometry to three Pu atoms. In the sixth Pu site, Pu is bonded in a 4-coordinate geometry to four Pu atoms. In the seventh Pu site, Pu is bonded in a 4-coordinate geometry to four Pu atoms. The Pu–Pu bond length is 2.46 Å. In the eighth Pu site, Pu is bonded to four Pu atoms to form distorted corner-sharing PuPu4 trigonal pyramids.
