Materials Data on Pu3Si2 by Materials Project
Pu3Si2 crystallizes in the tetragonal P4/mbm space group. The structure is three-dimensional. there are two inequivalent Pu sites. In the first Pu site, Pu is bonded in a square co-planar geometry to four equivalent Si atoms. All Pu–Si bond lengths are 2.90 Å. In the second Pu site, Pu is bonded in a 6-coordinate geometry to six equivalent Si atoms. There are two shorter (2.90 Å) and four longer (3.00 Å) Pu–Si bond lengths. Si is bonded in a 9-coordinate geometry to eight Pu and one Si atom. The Si–Si bond length is 2.38 Å.
