Materials Data on PuIO by Materials Project
PuOI crystallizes in the tetragonal P4/nmm space group. The structure is two-dimensional and consists of one PuOI sheet oriented in the (0, 0, 1) direction. Pu3+ is bonded in a 4-coordinate geometry to four equivalent O2- and four equivalent I1- atoms. All Pu–O bond lengths are 2.32 Å. All Pu–I bond lengths are 3.41 Å. O2- is bonded to four equivalent Pu3+ atoms to form a mixture of edge and corner-sharing OPu4 tetrahedra. I1- is bonded in a 4-coordinate geometry to four equivalent Pu3+ atoms.
