NaPuF4 crystallizes in the triclinic P1 space group. The structure is three-dimensional. there are three inequivalent Na1+ sites. In the first Na1+ site, Na1+ is bonded in a 6-coordinate geometry to six F1- atoms. There are a spread of Na–F bond distances ranging from 2.31–2.64 Å. In the second Na1+ site, Na1+ is bonded in a 6-coordinate geometry to six F1- atoms. There are a spread of Na–F bond distances ranging from 2.30–2.54 Å. In the third Na1+ site, Na1+ is bonded in a 9-coordinate geometry to nine F1- atoms. There are a spread of Na–F bond distances ranging from 2.37–2.92 Å. There are three inequivalent Pu3+ sites. In the first Pu3+ site, Pu3+ is bonded in a 9-coordinate geometry to nine F1- atoms. There are a spread of Pu–F bond distances ranging from 2.39–2.47 Å. In the second Pu3+ site, Pu3+ is bonded in a 9-coordinate geometry to nine F1- atoms. There are a spread of Pu–F bond distances ranging from 2.40–2.49 Å. In the third Pu3+ site, Pu3+ is bonded in a 9-coordinate geometry to nine F1- atoms. There are a spread of Pu–F bond distances ranging from 2.40–2.47 Å. There are twelve inequivalent F1- sites.
