The correct space group of NaPF6 x H2O.
The structure of sodium hexafluorophosphate monohydrate, NaPF(6) x H(2)O, has been inadvertently redetermined, revealing that the previously reported space group, Imma, was assigned incorrectly, with the a and b axes interchanged. The correct space group is Pnna. The program PLATON [Spek (2003). J. Appl. Cryst. 36, 7-13] suggested both Imma and Pmma as possible space groups, but only Pnna is consistent with the systematic absences. The inter-ionic and hydrogen-bonding interactions in the lattice form a three-dimensional network.
