Materials Data on PuSe2 by Materials Project
PuSe2 crystallizes in the tetragonal P4/nmm space group. The structure is three-dimensional. Pu4+ is bonded in a 9-coordinate geometry to nine Se2- atoms. There are a spread of Pu–Se bond distances ranging from 2.98–3.07 Å. There are two inequivalent Se2- sites. In the first Se2- site, Se2- is bonded to five equivalent Pu4+ atoms to form a mixture of distorted corner and edge-sharing SePu5 trigonal bipyramids. In the second Se2- site, Se2- is bonded in a 8-coordinate geometry to four equivalent Pu4+ atoms.
