Materials Data on PuH3 by Materials Project
PuH3 is Sodium arsenide structured and crystallizes in the hexagonal P6_3/mmc space group. The structure is three-dimensional. Pu3+ is bonded in a 11-coordinate geometry to eleven H1- atoms. There are a spread of Pu–H bond distances ranging from 2.15–2.39 Å. There are two inequivalent H1- sites. In the first H1- site, H1- is bonded to four equivalent Pu3+ atoms to form a mixture of corner, edge, and face-sharing HPu4 tetrahedra. In the second H1- site, H1- is bonded in a trigonal planar geometry to three equivalent Pu3+ atoms.
