The compound described by Pu3Si2 crystallizes in the tetragonal P4/mbm space group. There are two inequivalent Pu sites. In the first Pu site, Pu(1) is bonded in a square co-planar geometry to four equivalent Si(1) atoms. In the second Pu site, Pu(2) is bonded in a 6-coordinate geometry to six equivalent Si(1) atoms. Si(1) is bonded in a 9-coordinate geometry to two equivalent Pu(1), six equivalent Pu(2), and one Si(1) atom. is represented by the CIF file [CIF]
