Materials Data on PuI3 by Materials Project
PuI3 crystallizes in the orthorhombic Cmcm space group. The structure is two-dimensional and consists of two PuI3 sheets oriented in the (0, 1, 0) direction. Pu3+ is bonded in a 8-coordinate geometry to eight I1- atoms. There are a spread of Pu–I bond distances ranging from 3.11–3.44 Å. There are two inequivalent I1- sites. In the first I1- site, I1- is bonded in a distorted trigonal non-coplanar geometry to three equivalent Pu3+ atoms. In the second I1- site, I1- is bonded in an L-shaped geometry to two equivalent Pu3+ atoms.
