Materials Data on NaPu by Materials Project
NaPu is High pressure (38.9 GPa) phase of lithium-derived structured and crystallizes in the trigonal R-3 space group. The structure is three-dimensional. Na is bonded in a 11-coordinate geometry to five equivalent Na and six equivalent Pu atoms. There are a spread of Na–Na bond distances ranging from 3.33–3.49 Å. There are a spread of Na–Pu bond distances ranging from 3.41–3.79 Å. Pu is bonded in a 11-coordinate geometry to six equivalent Na and five equivalent Pu atoms. There are a spread of Pu–Pu bond distances ranging from 3.27–3.55 Å.
