Materials Data on Pu(IO3)4 by Materials Project

Pu(O3I)4 crystallizes in the tetragonal P4_2/n space group. The structure is one-dimensional and consists of two Pu(O3I)4 ribbons oriented in the (0, 0, 1) direction. Pu4+ is bonded in a body-centered cubic geometry to eight O2- atoms. There are four shorter (2.34 Å) and four longer (2.37 Å) Pu–O bond lengths. There are three inequivalent O2- sites. In the first O2- site, O2- is bonded in a bent 120 degrees geometry to one Pu4+ and one I5+ atom. The O–I bond length is 1.85 Å. In the second O2- site, O2- is bonded in a single-bond geometry to one I5+ atom. The O–I bond length is 1.81 Å. In the third O2- site, O2- is bonded in a 2-coordinate geometry to one Pu4+ and one I5+ atom. The O–I bond length is 1.87 Å. I5+ is bonded in a 3-coordinate geometry to three O2- atoms.
